Vagina Sisters

Two friends that are so close their menstrual cycles become in sync.

Girl 1: "Stephanie has been hanging around Erica a lot lately.. You don't think they're vagina sisters yet... do you?"
Girl 2: "I can't tell.. But I think I'd have to say so."

Sister Sally

Sister Sally is the random man in a group who's duty is to wear the skirt and be the dumpster for the day. Generally approached from behind, the skirt is pulled over the bussy's head to hide his ugliness.

Story's vary over the origin of the name Sally, from pirate days taking turns in the barrel to desperate sister who would do anything for attention.

We usually call him Mark.

Me and the boys drew straws but I think you just like to volunteer to be sister Sally.
