A block of frozen urine, thrown like a missile. Can also be a snowball, partially melted with urine, thrown with great force.

Get the pissile mug.
While taking a piss, the urine stream splits into 2 streams that flow in random uncontrollable directions due to the buildup of semen from recently busting a fresh nut. The piss usually gets all over the floor and the seat and even sometimes your clothes and bathroom towels. The aftermath can be devastating.
Gary: Dude I just got done nailing this fat chick. She had a bad case of FUPA and didn't...hold on a sec I will be right back. Gotta take a piss.

Frank: How long ago did you nail this fatty? Don't let your guard down, you may get attacked by ballsistic pissiles.
