To drench someone in sperm

A hulking, monstrosity of a male, swelled to intense proportions by his massive ego and genital package. His sole purpose is to appropriate your girlfriend and stick his dick in the "mashed potatoes". All this is concluded with a massive outpouring (a true 'gentleman's finish!) of man milk. Looks puerto rican, is generally unpleasant and should be shot on sight, or sodomized with a bandsaw.
