The frequent diarrhea that accompanies menstruation for many women. Prostaglandins are released during menstruation causing the uterus to contract and cause cramping. They also speed up the contraction of the intestines, hence large amounts of crampy, watery stool. Very similar to the hershey squirts, though period shits occur only during menstruation.
I thought I was in labor, but then I realized it was that time of the month so I went to the bathroom and had period shits.

A very defined genre of music; similar to but noticeably distinct from tampon toe-tappers and menstrual melodies. These songs usually revolve around themes such as "beauty", "innocence", "how hard this is", "blame", and "that bastard". This type of music generally serves as a warning signal to any nearby, unsuspecting males.
Example 1) Kris: Hey, man, I just heard some serious period music coming from Laura's room.
Tyler: That time again, huh? You get the ice cream, I'll lock the doors.
Example 2) "Hey, did you hear the new Melissa Etheridge album yet?"
"No, I don't get my period until Wednesday."
