salmon

The act of sneaking up on an unknowing victim at a bar or any other public place and quickly slapping them back and forth between their kneecaps with your hand, thus creating the sensation of a salmon tail swimming between the victim's legs. A successful salmon results in the person who got salmoned either buckling at the knees or attempting to high-step out of the salmon. Confusion/anger almost always results after getting salmoned; however, the salmoner can turn the victim's confusion/anger into embarrassment by quickly standing up and shouting, "YOU JUST GOT SALMONED, SON! WOOOO!" while pumping your fist in a ridiculously confident manner.
