A gay guy. Deragotorally said like faggot. Basically a guy that likes to give/receive from the rear, thus the mud reference.
As in a battle rap:
"Look how u dress and look how u act
You more light in the foot than tar is black, matter fact,
You must be out yo' head messin' with an all time great.
I swings from only one side of the plate.
So sorry fag, you run outta luck
I don't runs wit mud ducks
You or your lyrics will never get close to me
So stop kid before u show ur true inferiority
"
A mudduck is a life long nigger lover. It’s often because she lived in projects raised by a whore mom that taught her no morality or self-respect, or she had an overbearing daddy that she wants to embarrass at the destruction of her own reputation.
No, I’m not going to Beaver Falls with you. All of them hoes are either ugly, mud ducks, or both. I don’t want my pee to burn.
