Trayshon: Hey Aliyah. Aliyah: Leave me alone! *Aliyah storms off as Joanna comes up to Trayshon* Trayshon: Damn. What's up with her? Joanna: Aunt Flo paid her a little visit and will be staying for a few days, so deal with it. *Joanna walks off* Trayshon: I don't understand women. What does their aunt have to do with their moods? Oh! I get it! Yeah...I don't get it.
A euphemism for menstruation. "She" stays for around 5 days every month, can make you feel cranky and emotional, and you count the days until Aunt Flo leaves! Also featured in the South Park episode "Spooky Fish."
Jade: Aunt Flo has come to visit, she picked good timing! Melanie: Oh sorry hon. Stan: I wish Aunt Flo didn't have to visit now. Randy: Yeah, me too. But she only visits your mom for five days or so. I'll be out sleeping on the couch.
