"Type Shit" (also spelled "Type Shi" or "Type Shiii") is a slang term from African American Vernacular English (AAVE). It has many meanings but is often used to show approval, agreement, or describe something that's high quality or authentic — like saying "that kind of stuff."
You either understand it or you don't... Type shit.
Too real to fake, too rare to copy — that's the true meaning of Type Shit.
