The dump a female takes not because she actually has to but because her period makes her need to. This is due to the

uterus also signalling the
gastro system, making the bowels move more.

Tina: "Sorry but I had to take a
period shit."
*awkward silence ensues*
Tina: "That's right. You're not getting any tonight."
