my uterus hurts
a not-so-sneaky way of saying that you are on your rag or riding the crimson tide.  it is also a warning sign for men that they should either get away from the girl saying that her uterus hurts or kiss her ass and bring her comfort food.  :-)
Guy:  "Hey, what's wrong, are you sick or something?"

Girl:  "I'm not sick, it's just that my uterus hurts!!!!!"

Guy:  Thinking *maybe I should have walked away 5 minutes ago... fuck me... it's too late now.... oh well...*

Still Guy:  "Hey, I have this Reese's Peanut Butter Cup, I love Reese's... But I know you like them too... You need it more than I do, for both our sakes..."  *Guy hands Girl the Reese's*

Girl:  "Thanx."  *Gobbles up the chocolate!*   "But you still need to FUCK OFF!!!!"
