Shopping/menstrual cycle coincidence

I think "sklut" is an X-rated onomatopoiea.

Spoiler:

...for the noise a penis makes when it's moving around in a sperm-filled vagina, e.g. in hentai where the sound effects are spelled out, often in hilariously off-kilter English.

I've noticed that I shop more a few days before my period, but it's mostly for t-shirts, candy, and cat food (for my cat, not me).
