dead penis 

Noun:
A term used for some poor son of a bitch who finds out that his really hot girlfriend he has been showing off to his friends and family for the last 3 months is in fact a shemale.

Verb:
Dead penising
A guy who decides to screw his 'girlfriend' anyway after finding out she is in fact a shemale because he realizes that his whole fucking life is over anyway and he might as well get what he can. Usually followed by self castration while listening to some really shitty emo music.

Hey, what happened to Wally?

Hey man, leave him alone...he's just a dead penis now.

Poor bastard! By the blood coming from his groinal area, seems like he did some dead penising.

Dead bear penis 

This is a highly complex sex position where the woman is giving a blowjob and right as you're about to blow your load all over her face you take your penis out of hee mouth and cock slap the shit out of her and then cumming all over the slap mark. Thus giving you the feeling you get when you get a dead leg except in your penis.

Lois was giving me the best blowjob so I just had to pull a dead bear penis.
