cock thief 

An unappealing that woman that provokes performance issues in a male suitor.

The bar was closing and there was no one left except for this cock thief. I took her home and I was right.

describing someone so gay and sneeky that they can steal your anatomy and, at the same time, your heterosexuality without you ever realizing till it's too late.

Person one: "Hey! you best keep your hands cupped over your scrotum and cock, because that young fellow over there is one sneeky little cockthief!"

Person two: "Okay."

Similar to cock blocking, but it is where the female (cock) leaves with the cockblocker and their friends, not only leaving you cock blocked but also having the female stolen.
