An aggressive sexual act between two homosexual males in which both males must be large hairy men, otherwise known as "bears" or "yaks". The men must face off to one another on all fours while completely nude and attempt to establish dominance through only the use of their penises and makeshift yak horns made of dildoes attached with duct tape.
Adam and Jeffrey, both bears, slapped dildoes to their heads and began yakking when their wives went to the store.
