When a woman changes and discards her blood soaked tampon or pad in a public restroom which lacks trash bins, preferably in a park, a bathroom facility on a beach, or porta potty, where the filthy pad or tampon is first mummified; wrapped tight in toilet paper almost symmetrically into a square shaped mini diaper and then abandoned on the floor of the woman's restroom for a janitor or maintenance worker to pick up with a litter picker stick.
Brian: Yo John come quick! I just finished cleaning the women's bathroom and you gotta see this massive blood dripping poon bag that i just popped with my litter picker that was left on the floor of one of the stalls. Its absolutely fucking horrid! Mad skankasaurous rexs' here.

John: Ew yo why can't they ever throw them shits out for real! They really know how to make it nasty up in that bitch. Damn them dirty animals...
