1. To be laughing (sarcastically)

Laugh spawned in the "Community" section of the original AOL series. It is a sarcastic way of shrugging off a ill attempt at a flame, and/or libel. Something to the extent of "Whatever".
It is mostly used by the lesser l33t of the internet community to make up for the fact they are what they are. (Side note) Most counter-strike players use it.

The perfect Lare-Inducing word. Used to annoy others and can also be used as a replacement for the ever-boring lol

A form of laffter often used when you want to say something was funny.

Laff is your health on Toontown. Your Laff Meter tells you what your max Laff is, and how much Laff you have left. Every toon's max is at least 15, and the highest max you can have is 137. The only way for your current level of Laff to decrease is for a Cog or some other obstacle (such as a stomper or lava) to damage you. If you lose all of your Laff, you will go "sad" and be sent back to the nearest playground. Your toon will lose all of it's gags, be hunched over, walk very slow, and not be able to leave said playground until your Laff is at least 1. It's not recommended to leave with only 1 Laff point though, since virtually any attack will send you back to the playground, sad and gagless.

To love and laugh at someone at the same time.
Pretty much the two words "love" and "laugh" put together.

What I type online instead of lol... Because lol is overused.
