Like a Marmoset but completely different. These are things women have (boobs or a vagina), or it could be a penis. Anything sexual really, even a bummhole.

This word was originally made/ thought of back when I was in pre-school and it became part of a secret language with my friend. In later years the meaning of the words in that language were changed to suit our conversations and so it was born!
