A guy who likes to shake his junk a lot. Especially while wearing loose fitting shorts so that their junk makes a slapping noise against their leg. This is often perfomed naked in front of mirrors.
Thelma: I caught Brad shaking his junk in front of the mirror when he got out of the shower.
Beth: OMG! He is such a cock flopper!
