A nickname given to a person (usually male) with anger issues, and peculiar behavioural traits.
Often, this person can either be a manic depressive or a borderline schizophrenic because of the symptoms which they portray.
Although they are still able to get amazing girlfriends, they will often cause marital disputes by acting the goat and getting violent.

A word you just blurt out. It has a good citation, and it means nothing in particular. It's similar to the word "booby" but they are not the same.
You can also call someone a bibby which means they are good and lumpy.

"Omg look, Tony the Tiger is so bibby!"

Most commonly used to define a fat twat, usually over 21 stone. With jeans that dont fit and reveal the canyon of his arse, you may find many rock climbers within this canyon... they can fit.

How bloody Bibby is that?!?!
