My best friend tried to get her groove back, but her date was a huge hoodgie flop, so tossed him out of her bed.

Get the cum flopmug. 
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.

Get the Flopping Offmug. 
Term used to describe a situation where a man fails to sustain a pre-existing erection. Often applied to instances where sex was imminent but did not occur as a result of the flopped straight.
Mike was so horny after making out with his girlfriend for three hours, but when she took her panties off and he finally realized he was about to lose his virginity, he got so nervous that he wound up flopping a straight, much to her dismay.
