slit knit

Slit knit is a tampon, pad, or other menstrual fluid absorption apparatus, usually used as a pejorative and presumably in reference to post menstruation, implying a soaked, drenched, or dripping nature.

"I cant get comfortable today, this slit knit is really working to the side"

"ugh, I need rubber gloves to remove my slit knit, too much flow"
