To get wacked in the face with a penis

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."

To loot a body before it even hits the ground.

Smurf, or to be Smurfed is the state of mind where you are not sane. An example would be under the influence of any mind altering intoxicant, i.e. (alcohol, marijuana, pills of any sort, etc. )

When someone eats something blue, (such as an icy), you say they are smurfed because it looks like they sucked off papa smurf because their mouth is all blue.
