The female version of "Cock Blocking." When a girl is trying to get it in with a guy/girl but someone keeps interupting/delaying the process or eventually "snuffing" the situtation all together.
Teresa was trying to get laid last night and Kassandra totally was "muff snuffing" her at the party....bitch.
