noun. When engaging in sexual activity with a particularly flexible girl (gymnast, ballerina, etc.), lift the girl'
s hips and push them directly over her face, so that her knees are alongside both sides of her
head. By then penetrating her vaginally from the other side, there will be unavoidable scrotal slappage to the face. In this way, the testicles are
like small fists punching a punching bag, and her face is
like said punching bag. When performed at a rapid tempo, can be referred to as the speed bag. Note, this move becomes much easier to pull off when the
female has great flexibility or the male has really droopy balls.
After finding out that the girl sitting next to him at the
bar was a yoga instructor, Franklin's first thought was that he would take her home and have a
shot at the punching bag.
OR
As Bonnie was being slapped repeatedly in the face by Herman's testicles, she protested, "Hey! Easy there! What do I look
like? A punching bag?!" Herman responded, "Bingo."
