It depends on who I'm around and which jokes they have about it.
bf and I have a joke about it, but he calls it his "hideout".
one of my friends in college, it's c*nt. But not pronounced faintly, pronounced c*******Nt!! (he was always strange).
One of my best friends calls it "Hello Kitty" (started as a joke when he was intoxicated concerning red HK sleep pants). He probably wants to see it and I won't let him.
In the end, it also has a bunch of food names attached to it, thanks to other guy friends, like peach, and muffin too. Apparently, now that I think of it, it must be customary for my male friends to name my vagina. I don't really know why. It's not like I sleep with them or anything.
