look up any word, like sex:
When one, who generally does not consider one's self to be creepy or pervy, knowingly, and willfully adopts a much pervier persona for an unspecified amount of time. Most often this is done as a last ditch effort in order to acquire a mate for the evening.
Bro, I was at the club last night, was basically striking out with all the hotties in there.

Oh shit man, well what happened, I thought Rafi told me he saw you leave with a solid 7?

My friend, it was just a simple matter of Pervschwerv engage, and the rest, as they say, is history.
