1. When someone or a group of people are cracking up they are laughing hysterically, non-stop, and they might even be laughing so hard that they are crying b/c it is so funny.
Did I tell you what happened the other day? This woman was in the elevator with me and Tom, and she farted. Dude! it was an SBD! You could barely hear it, but I knew it wasn't me, and Tom looked at the lady in front of us - like eeeeeeew! I couldn't wait to get out of that elevator; it was so bad that it burnt the hair in my nostrils! We were cracken up about that all freakin' day! I still can picture her hahahaha! TFF!
