What is Flopsie?
1.
A female human takes her thumb and sticks it up a male human's anus. She then wiggles her fingers playing with the scrotum and says "FLOPSIE!" in a high pitched voice.
Last night I got the world's best FLOPSIE!
I tried to give Hank a FLOPSIE but I couldn't fit my FAT thumbs in his anus hole!
