A sexual stunt involving a male and female - preferably siblings or first cousins - where the man shoves his thumbs into the meatus of his urethra and wrenches his hands sideways with enough force to rip the penis in half down to the base. The remaining urethra hole in the base is then filled with whipped cream, after which the destroyed penis is promptly given a blowjob by the female.
Holy shit, Greg just got given the Alabama Banana Split! I think he's going to bleed out!
