Floor Dump 

When intentionally or not, a turd misses the toilet bowl, landing on the floor creating a nice surprise for future parties and cleaning staff.

Upon entering the stall, Humbult realized to his dismay that the last patron had not aimed sufficiently, and that he had not aimed his foot sufficiently either, landing into the waiting floor dump. Glancing down at the human feces in his treads, and faced with the possibility of cleaning it out, he wondered whether it would be better to just throw away the shoe. But then realizing that he would waste two good shoes, he made the tough call to clean it out with his fingernails and a folded up receipt.

Flash Flood Dump 

When you don't want others in a public restroom to hear your explosive diarrhea. You pucker up and you flush the toilet at the same time while you dump everything you've got. The toilet flush tries to cover your ass blast noise. Also gets rid of some lingering diarrhea smells.

Girl 1: Honey, I had to dump so bad but the bathroom was full and I didn't want to be embarrassed so I had to pull a Flash Flood Dump.

Girl 2: Dang I know what you mean hun, last time I did that the toilet cut off before I could stop. It was embarrassing. :/

floorjumper 

Someone that rides the elevator between two intermediate floors thus delaying those in it for the long haul. Ever heard of the fuckin stairs?

I could have made it to my desk by 9:00 if it wasn't for the damn floorjumpers holding me up.
