It’s an amazingly regional pronunciation.

I’ve also seen motherfucker, piece of shit, cuntbag, dipshit, loser, fuckwad, twat, asshole, worthless sack of shit, dickbag, scum, trash, dickless, sputum, cockknocker, fugly fucking waste of a life, soulless bastard…

And I am certain that this is not the entire exhaustive list.
