Another word for vagina. First used by a 3-year old boy named Daniel who just once called a vagina a kippie cup for no apparent reason. Also a humerous word to say and fun to say to people when they don't know what it means.
*Playing in a pool*
Nathan: (splashes water everywhere)
Kayla: Oh my God, you got my kippie cup wet!
Nathan: Oh jeez, it'll dry off eventually.
Kayla: Yeah I know, but still...
Nathan: Do I hear someone's baby crying? Oh wait a second, that's you!
Kayla: Shut up!!!
Nathan: Haha ok. (Can't keep a straight face and keeps laughing)
