Fudge Nucker is another word for a-hole or butt head. It could also mean a nut breaker (not the kind you eat) cuz' if you get offended girls you know where you're gonna kick a man.
Boy grabs girl's chest...

Girl-YOU FUDGE NUCKER! *kicks him where it hurts! OUCH!*

Boy-OW!

Girl walks away giggling with her friends.
