A nigga that ain't about shit. A deadbeat. Will never amount to anything and has no purpose in life, at all. And this applies to all ethnicities.
"We slept together and I haven't heard from him since."

"Girl, that's because he's an ain't shit nigga! Don't worry about him... move on!"

Get the ain't shit nigga mug.
An Aint shit ass nigga is a dude who will never amount to shit. He will never want to amount to shit, never will accidently amount to shit, and is never going to aspire to amount to shit.
Man that dude Chris Hendrix is an ain't shit ass nigga, he ain't got a job or a hustle and his dick is so small it looks like a pussy.
