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!

The action of not showing up, to a pre-set meeting or event. The use of an emoticon to symbolize the action of flop saucing may also be acceptable.

The most discusting floppy pussy you have ever seen. Or a dirogitory remark to say to someone you don't like.(Cause they dont know what it means either).
"This girl last night had the biggest Poon Flop i have ever seen."
"Get over here you fucking Poon Flop."
"Get over here you fucking Poon Flop."

In an office setting, coffee generally comes in little "sacks" of grounds that are proportioned to fill one pot. When one person puts in one package of coffee, he is said to have flopped a sack. Therefore, making coffee at work is to "flop a sack."
I went to the kitchen area and there was no more coffee left in the pot; therefore, I decided to flop a sack.
