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.
We had a rough nite at the bar, I go for a piss and when I come back here's this 7foot high walking hardon with his mitts all over my girls tits. After receiving a severe beating on his behalf, the last thing I remember is that sperminator walkin out, gettin half-blown by my girl.
