Bullfeather 

A person who wears a bullfeather is a person whose wife or girlfriend has cheated on him. The term comes from the "horns" on a cuckold -- the horn being the closest thing a bull has to a feather.

Just about any joke involving horns was considered hilariously funny through the 19th century, because everyone knew it meant the guy was a fool who was being cheated on -- the worst social disgrace for a man of that era.

John's wife is having an affair with Peter Quincy -- can't you see the bullfeathers on his head

Richard's girl sleeps with every guy in town. What a bullfeather he is!

Bullfeathers

Instead of saying 'bull crap' or any other term, use 'bullfeathers' around the 'bad word' freaks and you'll be safe.

Person1: Hey, did you remember the camera?
Person2: BULLFEATHERS! I forgot it!
