Uncle Tom and Aunt Flo 

The couple that comes to visit a girl once a month for a week. Tom meaning Time Of Month. And Flo meaning flow. Yeah...maybe you'll get what I'm trying to imply.

Boy: Is that bad?
Girl: Well they give me cramps and make me bleed..so yeah it's bad.
Boy: ...?

Uncle Floyd 

Occurs when a man has hemorrhoids and wipes blood from his anus. Compare to a woman's menstrual cycle and "Aunt Flo".

I needed a maxi-pad after that week-long cruise. Uncle Floyd came to visit unexpectedly.

Uncle Flow 

He visits all girls at "that time of the month"

"Hey Jenny, why are you so pissed off?"
"Oh it's nothing, it's just that my uncle Flow is in town, and he really makes me angry"

"Hey Jenny why are you taking your purse to the bathroom"
"Oh. I gotta text my Uncle Flow, he just had to call in the middle of class"
