When a man goes down on a women and he is damn creepy about it. He usually looks like a sad puppy dog and doesn't really know what to do or what you like. Creep cats can be spotted just by looking at them! Creep cats often have strange strangely beards, but are not limited to men with bad beards. The term "creep cat" comes from the fact that he is creepy and he is licking your pussy, aka cat.
It has not been confirmed as to whether women can be said creep cats.

Rachel said "Well when you get him into bed, you can prove me wrong. But I can tell just by looking at him that that man is a creep cat."
