(AKA: Mumblock) When a domineering mother dictates who you shall and shant speak to over myspace, msn or the phone.

(Note: Can also be used for fathers - Dadblock)
"Sorry, I tried to talk to you on the phone last night, but you've been Momblocked."

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..
