The exact opposite of a cock blocker. One who doesn't mind you smashing on a girl that you wanna hit, let it be one of her friends, her best friend, a girl you just met, her sister or other family member, or just simply her. Absolutely the best type of female any nigga could fuck with.
i met a girl named sabrina and she brought her bff with her too her name sasha i wanted sabrina but she already had a bf so i started talking to sasha and she didn't give a damn about it even though sasha is her right hander and i asked her if i could eat it and sasha said ask sabrina and she said yea so i got her in the sack and started eating her out which soon led to fucking her... man sabrina is such a cock allower i love her so much... (as a friend of course)

The opposite of cockblocking. An act of generosity that increases the chances of someone getting some action from another.
So I was just dancing by myself when this girl shows up, says "someone told me you were single," and we just start making out right there on the spot! I bet it was my friend B. who said something. He's always cock allowing for his friends, 'cause that's what bros do, you know.
