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. :/
