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.
