Unisex clothing that is solicited by a woman typically after the distraught realization that the only clothing available after a night of sleeping over is the tattered remains of a dress worn the previous evening. They are requested to avoid the embarrassment of the walk of shame. Plundergarments are almost always several sizes larger than the woman's size and are likely never going to be returned, and thus it is recommended the clothes furnished have little or no personal value.
"Hey girl, those are some nice boy shorts! Where'd you get them?"
"I was surprised when the center from the basketball team gave them to me as plundergarments after our fling last week. I want to keep them, and I haven't returned his texts asking for them back!"
Someone who has selfish sex with women with the intention to only gain pleasure not giving. In most cases occurs at the end of a night out, usually with a one nightstand, when someone is really horny but doesn't have much energy.
A pair of particularly scandalous or slutty panties; like the tiny, black lace, completely see-through ones that you feel awkward washing with the rest of your clothes because they are just that sexual, or Heaven forbid you use a public laundry room and they should fall out of the pile onto the floor before a crowd of judgmental eyes...or your mom.
