When a woman's menstrual symptoms are so severe (i.e., cramps, migraines, nausea) that she behaves as if she has Tourette's Syndrome.

Example #1 (without M.I.T.S.): "May I go in front of you because I only have one item?"

Example #2 (with M.I.T.S.): "Dude, you need to fucking move your ass or else I'm gonna knock you and your fucking kid out!"

Do you believe her? She's got some nerve.

She's probably suffering from M.I.T.S.

(I use this to describe mothers of other kids in my sister's very preppy, rich, school) "Of course she is a M.I.T(.S); look at her daughter!" "That is such a M.I.Tty mom." "Look at all of the M.I.T.S going to play country club tennis!"
