A repulsive individual that you typically encounter at a night club that makes aggressive advances towards unwilling women. As a result, the girls start clinging to you, and leads to a hook up.
Those guidos were so grinding up on every girl at Webster Hall. A cute girl gravitated towards me and we ended up hooking up. Who would have guessed those creeps would have been a reverse cock block.

An inverse cock block. The act of a wingman facilitating crumpification (see crumpify), except the hookup against all wishes; being made to crump someone you have no desire to crump.
Ben was just hiding in the room, while his roommate yelled out the window to a fugly. Before Ben knew it, she was up there and he could do nothing but crumpify. His roomate sat in the other room, grinning like a kid in the candy store, because he knew he just completed a huge reverse cock block.
