Person 1: "Did you hear John got a new girlfriend?"
Person 2: "No way! I'm going to go stalk her Facebook right now."
Person 1: "You can't see anything; I've already tried."
Person 2: "What a stalk blocker."

The act of one woman ruining another woman's chances for achieving something. The feminine version of cock blocking.

When someone blocks you from scoring with a chick. Literally blocking your cock from going into her pussy.
I wanted to go on a trip with my friends but i had a girlfriend. It was a trip to Amsterdam and i told my girlfriend nothing was going to happen and I would be faithful. My friend, Alex Barnett, went ahead and told her I wasn't going to be faithful. She went on a break with me. " He cock blocked me"

Cloth-Block, when you massage or rub a woman's vagina, or a man's penis while they are wearing either jeans, or anything other material.

friend: i dont know... damn dude that was some hardcore memory block.
