When out with a group of your buddies you 'escape' or 'eject', early and without warning to get home 'on time' or because you're too loaded, on a trip back from the bathroom or by sneaking out a side or back door.
"Where the hell is Grease?" "Haven't seen him for a while. He was so gooned, he must have Houdini'd."
Another delightful twist on the original houdini, to perform the Houdini Darth Vader correctly you should be breathing heavily in the ladies ear as though you have a respiratory condition. Upon reaching climax, spit on her back, when she turns around shoot your load in her face and shout 'I AM YOUR FATHER' to which she should reply, 'NOOOOOOOOOOOOOOOOOOOOOOO'
"Whoa Steve, your mum really freaked out when I Houdini Darth Vader'ed her last night."
"But if your her father, does that mean we're related???"
Similar to the houdini cheesecake except your mate runs out the closet and bums you. All gay men are called Darren hence the name of this rather cynical surprise act.
"Darren you twat, can't believe you tried the Houdini Darren Delight on me. It's a good thing you are a soft arse otherwise you may have overpowered and bummed me!"
