The overdramatic, hurtful, mean, rude things a woman says when she's starting her period.
1) Boyfriend: "I love you, Honey." Girlfriend: "Eat shit!"

2) Sorry, I didn't mean to say that. I just started my period and I've got menarche mouth.

3) Bitchy went crazy...had a bad case of menarche mouth. She be flowing for sure.
