LOL - used in messaging or slang speech when something bad/funny/embarrassing has happened to someone, is meant to show amusement ;) but is used when people have a dead straight face x_x

E.G. in messaging

person 1: OMG did u see what happened to person 3 today in math?!?!

person 2: no what happened

person 1: teacher asked them a question but they had AirPods in and didn’t hear him, so teacher came and shouted in person 3’s ear and person 3 went bright red it was so funny - I was LMFAO

person 2: LOL
