Bundig
A positive nickname only good enough for the closest of friends. Can be used in the context of 'cunt' but in a positive way. It can not be used negatively. But it can be used in a way for a bit of banter. "Mardell you squeaky bundig."
"Josh was a bit of a dickhead but at times he can be a bundig."
"Oi bundig, how's it going mate?"
"Oi bundig, how's it going mate?"
bundigent
Not exactly what one meant.
Though his use of the phrase "self-defecating" was bundigent, people still understood.
