Chatroom · 5 November 2026 · 1 min read

Every txt cost money and every keystroke counted, so we invented a whole language. Here it is, for anyone who's forgotten (or never knew).

Coming and going

SlangMeans
brbBe right back. Usually meant "someone needs the phone line".
bblBe back later. Longer than brb.
g2g / gtgGot to go.
ttylTalk to you later.
l8r / cyaLater / see ya.
wbWelcome back. The polite reply to someone returning.
afkAway from keyboard.
gnGoodnight. Followed by 20 minutes of not actually leaving.

Asking questions

SlangMeans
a/s/lAge, sex, location. The classic chat room opener.
wbu / hbuWhat about you? / How about you?
wydWhat are you doing?
supWhat's up?
nm / nmuNot much / not much, you?
y?Why?

Reacting

SlangMeans
lolLaughing out loud (usually not out loud).
roflRolling on the floor laughing.
lmaoLaughing very hard.
omgOh my god.
jkJust kidding.
oicOh, I see.
kkOkay.
npNo problem.
idkI don't know.
tbhTo be honest.

Secret codes

SlangMeans
posParent over shoulder. Change the subject now.
p911Parent alert, same thing but urgent.
hugsA virtual hug. Asterisks meant an action.
...Something is wrong and you have to ask.

And the emoticons

The other half of the language was emoticons: :) ;) :P (Y) (L) and the rest. They have their own cheat sheet, and on Chatroom they turn into faces as you type.

Should you still use them?

Absolutely. In the Throwback rooms, a well-placed "brb" or "pos" is half the fun. Just maybe skip a/s/l as an opener; "what was your old screen name?" works better. Here's how to pick yours.
