monkey running 

Egging but not as douche-baggish. You throw bananas at passing cars from a hidden position. If they spot you, you run like crazy. It does not completely ruin the car like and egg but is just as fun.

Money Under Mout Runnin 

A term that is used mostly by African Americans when they want to express their opinions but can not think of the correct words. This phrase was made popular in the YouTube video "Mother fucking Bootleg Fireworks-Subtitled Version"

Before the African American mans friend lights the fireworks he exclaims MONEY UNDER MOUT RUNNIN!
