Houdini Torpedo 

A Houdini Torpedo is when you drop a Deuce in the toilet bowl and the trajectory and velocity of the fecal matter leaving ones anus causes the elongated mass of shit to disappear out the drain pipe without leaving any evidence of its existence in the bowl.

Honey, you won't believe what just happened, I took a crap and after wiping my shit stained ass , I placed the used toilet paper in the bowl only to realize I produced a Houdini Torpedo, it was like majic , my shit had completely disappeared ! I

Ghost of Houdini 

When a man is lying in bed on his back and he gets a hard-on, it rises beneath the sheets appearing as a ghostly figure in the morning light. True to the spirit of Houdini, the ghostly erection is likely to disappear soon after it arrives, possibly into the woman beside him.

Jane: Baby, look at the sheet near your crotch!
Kevin: Shh, baby. It's the ghost of Houdini.
Jane: Really? Is he friendly?
Kevin: Oh yeah. I think he wants a kiss.
Jane: Okay.

Purple Houdini 

The bruising that occurs when an over ambitious vagina technician gets a little too close to the vaginal lips during a Brazilian wax job.

Michele's attempt to spice up her love life went from high to low when she realized her personal waxer at the Pretty Kitty Boutique left her with a Purple Houdini instead of a nice, smooth snatch.

Hoodini 

A joke that was recently made by 6 youtubers with the user Vanoss Gaming in it. It has become an inside joke that has become a meme. The actual joke was created when Vanoss Gaming read off a joke about an owl (since his gta v character has an owl mask) who is a magician. (Hoo)dini was the punchline.
Often when one of their fans asks a question others will reply with Hoodini.

Evan: Alright, what do you call a magic owl?
*Short pause*
Evan: HOOdini

When in the act of having anal sex with your partner, you say you have to pull out for a second (to put on another condom or some other reason) then your friend switches in and starts having anal sex with her while you sneek around outside and wave at her through a window. then when she turns to look who is having sex with her your friend punches her in the face and at the same time you punch through the window.

Dude, she was so freaked out when me and my friend Double Hudini smashed her!
