Lol

originally an abbreviation for "laughing out loud' some people still use it like this but it has been changed into an awkward convo - space filler or if you're mad at someone but don't want to show it.

"Why would you do that lol." (mad)

{hey beautiful what that mouth do} "lol" (awkward)

What did the traffic light say to the car?- Don't look now. I'm changing. "lol that's a good one" (humor)
