Ninja

When you disappear behind a thick puff of smoke. Works better with a hookah; inhale the smoke and then slowly breathe out. Make sure to be standing near a place where you would hide yourself.

Ambrose - Okay guys, check it out! (creates a huge smokescreen and disappears behind the curtain)
Buds - WTF? This dude must be a fucking ninja!

Ninja

An alternative substitution for the term "nigga"

A nicer way for non black kids to use the term nigga without actually using it. Even though nigga is not a racist term, it can be misconstrued and possibly be offensive to some people. Ninja is a fly way to convey old to the new and may just save someone from an ass whippin'

Yo what up, my Ninja?

That's my motherfuckin Ninja!
