The Jellyfish 

An in-experienced form of foreplay. Handjob gone horribly wrong.

The Jellyfish: when a female gently plucks the head of an erect penis using her forefingers and thumb in an upwards motion. This resembles a jellyfish swimming. It is also an extremely unsatisfying act.

The jellyfish 

When a man ejaculates into his hand, then spreads his semen on his shlong, he then dips it in a glass of salt water, and proceeds to urinate in the glass, and a woman drinks the contents of the glass, leaving her with a sting in her throat

Man, this girl as a freak! She asked me to make her The jellyfish

The Stunned Jellyfish 

When you stick a tazer up a girls vagina (as you would a dildo) then she is in a dormant state and you fulfill your sexual needs such as boning her as you both slide down the stairs on a sled or as you make another girl have sex with her. This all happens all while she eats her favorite marshmallow.

I completely got her in a the stunned jellyfish.
