welsh alternative for mother fucking bitch..see mofo:
hort for mother fucker. A person who thinks they are the shit, dressed down with sagging pants, a high need for a belt, too much gold to make the national reserve jealous, and an attitude that stems from not having parents who knew how to refrain from the use of crack cocaine.
A mofo is the biggestcocksucker in the whole world such as my friend Neaku, who has men up his butt constantly. A mofo is also a person who always spreads rumours about you like a little bitch
