Internet slang

Template:Cleanup-ipa

Internet slang consists of slang that users of the Internet have developed and utilized. Many of its terms originated with the purpose of saving keystrokes, as a result many use the same abbreviations in text messages (see txt). The terms often appear in lower case, with capitals often reserved for emphasis — the pronoun "I", for example, often appears simply as "i".

Common disclaimer phrases (or parentheticals) also often contract into acronyms — they tend to occur at certain points in a sentence, which can facilitate decoding. Some of these include:

IMHO (in my humble/honest opinion)
AFAIK (as far as I know)
AFK (Away from Keyboard)

The untrained eye often finds Internet slang difficult to interpret because content in spoken language that speakers convey in the intonation and tone of the voice, such as sarcasm, do not readily transfer to written text.

Emoticons (or smilies) such as ":)" can go some way towards clarifying emotional intent in Internet messages. As with other Internet slang, netizens may use emoticons both genuinely and sarcastically; for example the ":-P" emoticon, which can express either genuine amusement and a sense of fun, or express a negative sarcastic comment on something another user might have said.

Certain online personalities, among them Jerry Holkins of Penny Arcade, have begun to decry the usage of Internet slang, going so far as to refer to it as "the crude truncations of the lower classes." [1]

Although Internet slang has a close relationship with leetspeak, only online gamers traditionally used leet, whereas much larger groups of Internet users commonly use Internet slang.

Chat acronyms or chaq (pronounced "chalk") originally developed on pre-Internet bulletin board systems. A handful (for example, ASAP, PO'ed) far pre-date computers. The three-letter acronym (TLA) remains one of the most popular types of abbreviation in computing and telecom terminology and slang. Similar systems have since come into use with users of text-messaging wireless telephones.

Contexts

Internet slang occurs in various means of electronic communication. In order of most to least frequent use:

Text messaging on cell phones involves slang even more heavily abbreviated than Internet slang, due largely to the relatively inefficient text-entry method.
Instant messaging provides a very common medium of use, since brevity forms an important part of communication in this environment. Emoticons often convey emotions in instant messaging.
Chatrooms, especially those connected to instant messaging, often use abbreviations and emoticons.
Chatrooms on IRC sometimes use abbreviations, and more frequently lowercase text (for speed) and emoticons. IRC-users often employ emoticons to express sarcasm.
A few Internet forums use Internet slang. This may happen for the sake of speed, as in forums like FaceTheJury; or, on forums where more "proper" grammar prevails, it may give a sarcastic tone to speech, such as FYAD on the Something Awful Forums. Forum-based slang tends to appear more specialized and localized than other types of slang.

Internet abbreviations evolve and change continually. Online games provide a good place to observe language variation in use. Often, people uninterested in computer programming do not understand the more classically "nerdy" phrases like "2B||!2B" (which means "to be, or not to be"), thus they become useless or appear only in minority forums. From the days of FIDO mail when most computers ran DOS we find <G> meaning "Grin", <BG> "Big Grin", <VBG> "Very Big Grin", and of course <VBSEG> "Very Big S*** Eat*** Grin".

Common Internet slang

The vocabulary of Internet slang draws from many different sources — typically environments that placed value on brevity of communication. Some terms, such as FUBAR have roots as far back as World War II [2]. Other terms come from more recent forms of communication, such as TTY and IRC. With the rise of instant messaging services (ICQ, AOL, and MSN, among others) the vocabulary has expanded dramatically. Some of the most commonly occurring elements of this slang include:

lol – laugh(ing) out loud/laugh on line/lots of laughs
brb – be right back/bathroom break
gtg/g2g – got to go
l8r or cul8r – (see you) later
lmao – laugh(ing) my ass/arse off.
rofl – rolling on floor laughing
sry – sorry
cya or cu – see you
ty – thank you
gg/gj – good game/good job
ttyl – talk to you later
bbl – be back later
thx/tx/tnx – thanks
ta – thanks a lot
ihm – i hate myself
wombat – Waste of Money, Brains, and Time
nm – Not much (sometimes never mind)
nvm – Never mind
np – no problem

Aside from instant messaging programs another realm full of online languages exists: the Internet gaming world. One of the most popular forms of video game slang has become known as H4X0R or as 13375P34K (in leetspeak). For parents today, learning the online language can play an important role in maintaining the online safety of children. An article produced by Microsoft may help parents begin to understand some of the things their kids say in-game. (Many of the more knowledgeable "geeks" consider this article a joke, especially for Microsoft's attempts to interpret 1337 speak.)

Note that the many "true" computer gurus, hackers and coders regard leetspeak as a pathetic trademark of a newbie or of a show-off. Gurus, hackers and coders almost always use leetspeak sarcastically. They label the use of leetspeak, excessive use of abbrevitaions, and incorrect spelling and grammar as rude and usually indicative of a script kiddie or of a computer newbie.

Effects on wider language use

Users sometimes make up Internet abbreviations on the spot, therefore many of them can seem confusing, obscure, whimsical, or even nonsensical. This type of on-the-spot abbreviating leads to such things as: OTP (on the phone) or the less common, OPTD (outside petting the dog). Another feature common to Internet communication is the truncation and morphing of words to forms that users can type more readily. These may one day creep into common usage and end up in the dictionary. Examples of this include:

addy — "Address" (plural: "addys")
compy — "Computer" (already has made the leap to common spoken usage)
dun — "Don't"
ima — "I'm going to", "I'm a gonna" (predates the Internet).
lappy — "Laptop"
pic — "Picture" ("pics", "pix" or "piccies" for plural)
proggy — "Computer program"
prolly — "Probably" (The Oxford English Dictionary traces this usage back as far as 1962)
awsum — "Awesome"
siggy — "Signature"

The form "teh" offers a special case of this transformation. This originated as a corruption of "the", and often pops up spontaneously when typing fast. So common has it become, in fact, that it has made the jump to purposeful usage. Typically it occurs in situations where the writer presents as self-consciously enthusiastic, mimicking the less-grammatical Internet newbie: "That movie was teh suck!!", "The fight scene with all the Agent Smiths was TEH AWESOME", etc. It occurs most commonly in "teh suck", "teh lame", and "teh shit", although "teh shit" has the same meaning as cool or "teh cool". This sarcastic usage originates with JeffK.

Similarly, netizens may use the word "liek" or "leik" as sarcastic mis-spellings of the word "like", as in "I LIEK PIE". It often implies an insult to one's intelligence and/or typing ability.

The word newbie occurs almost exclusively to refer to all sorts of new users of an Internet forum or starters in a particular field of activity. It does not function as a pejorative term per se, but can do so when combined with RTFM, etc. "n00b" has much more derogatory implications than "newbie".

"own" has become a mainstream word for "to completely dominate". It probably pre-dates the Internet in some usages. It also sometimes appears spelt "pwn" owing to a common typing error due to the proximity of the "p" and "o" keys on a QWERTY keyboard. This spelling "error" sometimes get verbally pronounced "Pone" or "Pawn", although more commonly Internet users simply pronounce it as "Own". "Pwn" originally came from the use in the game Quake of the phrase "Pistol Owned".
