Cuck is an onomatopoeia derived from the moaning sound white supremacists make while fantasizing about getting fucked. It is NOT, as some trolls suggests, derived from "cuckold" - a fantastical troll logic only horny White Supremacists would believe in.

Until White Supremacists find better ways to get people to fuck them, the word cuck serve as an important cultural clue to help us better understand the unwavering depth of their erotic desires. It is also recommended to report them for sexual harassment should they call you such a thing.
