Get the California snowball mug.
A practical joke or stunt that includes a man ejaculating into his hand before throwing the sperm deposited onto someone else. The sperm can be mixed with a clump of dirt to better resemble a ball. This stunt can be famously seen performed by Stuart Rudin in the film 'Silence of the Lambs'.

A California snowball fight arises when hobos take turns throwing hand-formed balls of fresh-squeezed, or old feces at each other, unsuspecting bystanders, pets, indiginous wildlife, and pretty much anything within throwing range. There are no victors in this game, only very smelly and very pissed off victims.

It is such a common occurrence that the State once considered sanctioning a legitimate sports league for it, but during the testing phase, a new and rampant strain of hepatitis -now called hepatitis Q- broke out, and everyone's TVs were also stolen.
Oh man, I got caught in the crossfire of a California snowball fight, and now I have the worst case of pink-eye EVER! Where the hell is my TV!!!
