Jane-doe's (pronounced "JAYNE-doughs") are the random panties or other bits of women's underwear you find scattered around your apartment. A true pair of Jane-doe's will have no identifiable owner whatsoever, and as a result of this may stay on the floor of your flat for weeks on end, collecting dust as you desperately ponder what is either simply a deteriorating mental state, or a complete and total breakdown of sexual standards. See also: John-doe's.
Dude, I've got no idea where that bustier came from. It's a total Jane-doe.
I get so much ass my flat is littered with Jane-doe's!
Yo man, what's with the Jane-doe's? Are those your mom's or your sister's?
