Kuntzilla 

When you experience explosive actions and difficulties with your baby mom about children issues after she has cheated on you!

A kuntzilla is usually a larger figured person that has light coloured hair and is not trustworthy in any relationship!

After being cheated on , I asked the children's mother if we should put them in therapy and she went full blown kuntzilla mode and flipped her shit!

Katzilla 

A fierce destructive force, known for her outwardly sweet demeanor and tendency for others to underestimate her. However, beneath this hides a solid resilience and determination to fight for what is right, specifically against those who would seek to threaten and strong arm her and others through illegal and unjust means.

This fearsome creature was finally spawned in 2013 in the American Southwest after years of intimidation, mistreatment, and neglect and is rumored to currently be stalking about Maricopa County in Arizona.

The name was originally coined by a resident of Arizona during an immature, insecure, and vulnerable moment (all of which are not uncommon for this individual), but it has since taken on a life of its own and empowered the "monster" for which it was contrived.

cuntzilla

a girlfriend of someone who always keeps one from going out to hang out with his friends. that one is usally pusswhipped, and that means you arent a man if you cant (1) control your manly needs, (2) you cant control your lady. a cuntzilla is mostly needy and a control freak. they tend to be either ugly or think their shit dont stink.

cuntzilla

A person (generally female) who acts like a cunt in a grand or monstrous manner. Being a cunt in a big way, using the word cunt to demean the person the way you would call someone a dick. Calling them a dick or a cunt in this case is such an enormous understatement that the word must be monstricised to encompass said persons cuntiness.

That bitch is a cuntastrophy, she is cuntzilla. Watch out for the cuntzilla at the bar. My girlfriend was great then she found someone better and turned into cuntzilla so I would break up with her. Cuntzilla awaits! (nee manager or female boss)
