Means fucked. Etymologically derived from the fact that the word fuck is used as all parts of speech. For example, "I'm going to fucking fuck your fuck-nut face up you fuckity fuck-wad." Similarly, Smurfs would use Smurf with the same versatility. For example, "Gargamel, I'm going to smurfing smurf your smurfing smurf-nosed face, and then smurf your cat Azriel."
Person1: So you really like this guy?
Person2: Yeah, he's not insane, smart, has a job, and he smurfed me like a school-girl.
