it is another word for vagina, but more of a girly term used by tifany k. jen k. erin M. and myself. we like to use this word becuz it is nicer and clever, other than just saying, "oh guys look what i have sprouted on my VAGINA!" instead its "oh look! my pee-china has sprouted odd figures!"
"oh my gosh mommy, your so hott, let me touch your pee-china!"
