A term used to describe an extra bitchy female that sounds less offensive than saying cunt but is really just as bad in meaning. By choosing this word, you are decreasing the chance that other girls around you will get pissed at you for insulting their entire sex. And it's funny cause it rhymes with macaroni. Who can get mad at that? It's adorable.
This bitch in Mandees was pissing me off big time but I was sexually outnumbered so I chose my words carefully and called her a cunteroni. It was great, the other girls just laughed and agreed. I still shielded my balls though, just in case.
