Cousy 

Cousy is anything you want it to be when it needs to be.

Sarah has been being a little cous/y lately and it’s really been bugging me.

If you touch me one more time, I will slap in the cousy.

Coist 

A mixture between "cunt" and "moist." Many women are other grossed out or severely offended by these words, therefore it's been combined.

Sidenote: "Cunt" can be alternated with "cooze," "clit," or any of your own C words.
