Going 'ALOL'

Laughing out loud in a situation where you shouldn't be laughing at all.

Going 'ALOL':

Friend 1: Did you see that disabled person fall into the water fountain?
Friend 2: Yes, I almost went ALOL.

In the park yesterday, Rachel went ALOL when she hit an old lady with a Frisbee and her false teeth fell out. Apparently the pensioner needed stitches.
