naasik
A black dude with a face like a monkey. He's got the skills to beat you in basketball, but he'll cheat on you and has a tiny pecker.
He's got a face like a monkey and a pecker like a shrimp. That's a naasik.
He cheated on my cousin with her best friend. Naasik behavior, pure and simple.
He said he'd help me with my math, then he went to the gym. Classic naasik.
