Some bad bathroom humor...basically it's saying, you're f**ked because you're out of toilet paper....being a young lady, you should've gotten that one twice as quick...LOL
haha! one time i saw a little poem in a stall that went a little something like this:
Here I sit,
broken hearted.
tried to shit
only farted.
pulled up my pants
took a chance
tried to fart
i shit my pants
