the act of smacking a vagina in order to inflict painful pleasure. The accepted technique is useful when a girl is on her period, since muff slapping does not involve penetration. Advanced slappers indulge in a pre-slap lick of the fingertips (in order to "get it wet"). Most commonly used on crack whores or slutty broads.
Ryan: Yo, did you fuck that bitch last night?

Ryan: Tiiiiiiiiiiiiiits!

When a woman blocks another woman from a potential hookup with a guy. Usually involves unsubtle flirting. Oddly, women with boyfriends or husbands perpetrate the muff block and have no romantic interest in the guy, shutting down their available girlfriend. Female version of the cockblock
1) I think Maryanne is muff blocking Allie. She walked right over and starting rubbing his shoulders and stroking his hair while Allie was talking to him.
2) Carol did a classic muff block when she sat on Rob's lap right in front of Heather.
