Meaning

A variant of "XX: Are you being polite?" commonly seen in bullet comments. Has stronger tone than the original. By putting "polite" at the beginning, it modifies the subject XX; the remaining "ni ma" becomes a homophone for "nm" (your mother, a curse). Creates a funny contrast effect. Example: In a jaguar hunting caiman video, use "Polite crocodile: your mom."
