(V.) to talk down on somebody, to patronoize in a very obvious manner

Renz: "Why you always putting a masad on people?"
Hope: What's a masad?
Renz: You know, like fronting ...being fake.
Hope: Oh you mean a facade! Geez, Renz! I told you never to use words you don't understand or can't pronounce!
Renz: Why you always have to be downing a brother?
