Mom Block

When in the act of fun, in a crowd, at a concert, or being bullied, you are under mothers protection. Where the mother shields her child and sucks the fun out of situations as defense mechanism to hostile outsiders.

Brad: Dude, that kid is so getting mom blocked.
Matt: Oh damn, she's putting up a full shield. . .and she's like 60..

My mom came in town to visit me and totally mom blocked my hook up.

mom cock block

When your mom catches you bringing a girl into her house and prevents you from banging her.

"Dude, I got mom cock blocked. I was just about to bang that chick but then my mom came in and made the slut go home."
