A phenomenon that can occur to men's peni while engaging in a MMF (male-male-female) 3-some.
While DP (Double penetrating) the woman, a peni may sometimes go astray and flop out of it's respective slop socket. On rare occasions, when this occurs, the peni may also bounce, or prickochet, off the other wad-rod.
Dude, your cock just prickocheted off my jolly-log! Keep to your side of the taint-scape, you fag!!
