A rare disorder related to Stockholm Syndrome where upon being mugged by a Hobo while taking a piss, the victim takes pity on the mugger and gives him a BJ. In an effort to comfort the Hobo and gain trust, the victim will swallow the Hobo's man custard. A bond develops between the mugger and victim, to such a level where, as a sign of gratitude, the Hobo returns the victims wallet (sans £60).
Mick: Dave, where you been?
Dave: Just been hangin' a piss in that seedy alley way, some cunt just stole my wallet Mick: Right, so how do you explain the jizz running down the side of your mouth?
Dave: What? fuck that, someone get me a crowbar, I'm gonna go after the cunt who stole my wallet
Mick: Dave, face it, you're a Hobo Semen Eating Dude.
Dave: Dude, I'm strugglin'
Verb describing a rare phenomenon occurring between two men whereby the man administering butt sex to the other performs a rusty trombone (it is the courteous thing to do), catches the sperm in his hand, slaps the receiver in the face with his jizz-filled hand, and slowly pulls his hand away to create a web-like effect. And hence, man #1 has spidermanned dat dude. This phrase was popularized by the underground rap sensation Cabin Boy's song of the same title, "Spiderman dat dude (9/11 I'm sorry...)(Cabin Boy Tell'em)."
