Top Definition
When one fucks somebody from behind, but through their chest, making their love truncheon penetrate their still beating heart, and getting near climax. At this point, another person will walk up and see the rod pressing against the flesh, the result being the flesh moving up and down to that persons eye. Entranced, that person will stare until the spam lance breaks the flesh through the persons chest in an alien like fashion and squirts the unsuspecting observer in the eye.
I gave some dude at that concert last night an alien infestation.
