Xeno Male
A male that has been an infected by a virus of extra-terrestrial origin and so is no longer confined to the traditional human socio-sexual hierarchies of Alpha, Beta and Gamma males. He cares not for sex or status and seeks only delicious flesh to satiate his xenomorphic hunger.
I went on a date with Chad last night, and he tried to lay his eggs in my brain again. He's such a Xeno Male.
