What is Monkey Jump?
1.
When you call a black person a nigga (or nigger) and they call forth several of their friends to beat you up.
"George called Jerome a nigga, ya' know, trying to fit in, so Jerome takes offense and gets Jequim, Tyrese, Tyrome, Darius, and Frank to monkey jump his ass, even though when they called him cracker two minutes earlier, he couldn't do anything about it or it would be racial!"
