(Jim hits his penis against Bill)

Bill: Da fuck?! Put that away!!

Jim: Sorry man. I just fling donged you! I clean it up.

flint knapping

Flint knapping is when two guys put pieces of flint rock between their buttcheeks and moon land each other. The friction generates a spark which tickles their anus hole and gives the Flint knappers extreme pleasure.

Bobby and the boys are planning a flint knapping event for the club competition this weekend.

Flinstones Push-Pop

A sexual act performed on a male that requires a finger be inserted into the anus, thus causing an erection that is directly proportional to the depth of finger penetration.

“Christine only passed nursing school because she gave the professor a Flinstones Push-Pop before every exam!”
