When you lean forward usually to pull up your pants in a public bathroom, and your turd breaks off long ways and does a front to back sideways splash, splashing toilet water from the bowl up onto your ass
I was dropping a deuce at work and an coworker walked in, I pulled my pants up from around my ankles as I was braking one off and it did a Smelly Flop into the bowl.

Auto erotic genital manipulation performed without the aid of one's hands. The flaccid penis is thrust about with aggressive hip movements and shuffling for between one and two hours or until erection occurs. The flopping off continues for another three to twelve hours when climax is finally achieved. Women with large clitori or labia minora may also engage in flopping off.
Guy 1: Man, I was flopping off like crazy yesterday. Took me like 13 hours but it was sweet, yo!
Guy 2: An all day floppoffathon? Gross!
