An actual block of wood with the words COCK BLOCK written on it. It is used when a male is talking to a female, and another male walks up with THE COCK BLOCK, sets it down in front of the male and takes over the conversation with the female.... there are several variations of the cock block... "The Pocket Cock-It" (a pocket sized cock block), "The Twat Block" (the female version of the cock block). Developed by college students in Visalia, Ca.
"Talen was talking to this chick when all of a sudden Bryant walks up with THE COCK BLOCK, and sets it down in front of him."
