Period Fencing

A sport originating in the eighteenth century in which two women settle a dual of pre-menstrual angst by scissoring until one party passes or taps out.

Connie: Why the hell am I so pissed whenever you're around!?
Gertrude: Why don't you pull your bottom lip over your head and swallow!
Connie: I'm going to...
Alan, interrupting: Are you two PMSing or what? You need to settle this with some period fencing.
