a deliberate punch to the scrotum. usually causing a brief blackout, mild neausea, pins and needles in the legs,and the possible loss of balance. a wowzerdoo can NOT be performed by a girl. it is a sad man revenge tactic, often employed by those who cannot fight fair.
a wowzerdoo is acceptable if you have caught your friend sleeping with the same girl as yourself
