What does it that mean to you? In what circumstance might you hear someone utter that? Those who don't want to play move on.

It is rather witless on many levels.

Up the kitty?

Pussy sounds so warm and inviting, perhaps down to earth. Maybe it is something a woman might say to another woman who is uptight or overly competitive or to imply the woman has too much testosterone (speaking figuratively of course) or maybe to an overly aggressive man, or a man who enjoys pussy a little too much. You might suggest it to a friend who you feel might benefit from gender reassignment (the words sound like something from the movie "Sleeper" by Woody Allen). A real put down would be to suggest a he to she procedure to a woman.

The opposite, of course, would be an additictomy.

hear regularly? If it is, have you considered a procedure for yourself?  

it just sounds like something that would be fun to say.

By who ... lol
