A sexual fetish in which one or more people cram peanuts into their penis, preferably through the urethra.
This stimulates orgasm by either the peanuts stimulating the prostate or by preventing the bladder from voiding, causing it to stretch and stimulate the prostate.
Both of which have the downside of the sensation of passing a kidney stone, however, some people get turned on by the pain.
Yo dude! I just tried Peanut Penis when I was horny last night, it really hurt, but it felt good too.

Other dude: thanks man!
