A popular (Yet sick) clopfiction genre based on the act of snuff.
My god, this fiction is Snuffed!
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.
