What somebody types on IM, MySpace, Facebook or Bebo which means "What you said was sorta funny, but I really can't be bothered laughing, and you can't tell that I'm not."
Tina: "Hey Bob, remember yesterday?!"
Bob: "Yeah, LOL."
lol inside of brackets is basically like a super LOL because it sorta looks like a tie-fighter.
Laugh out loud emphasized.
wow, that is so funny... lol
and this site doesn't let me use brackets in the example because it uses them to link to other words. lame. but, you get the idea there's an open bracket, then lol, then closed bracket. this almost isn't funny anymore because I had to spell it out to explain it.
