A place where things of a dirty nature are abundant and expected.
Guy 1: Dude that's nasty!
Guy 2: Nah its not that bad... It's not like I got it from zayna's sockdrawer or anything....
A drawer where many sexual and non kosher things show up. Full of dirty secrets, used socks and so on.
John: Jamie where'd you find that dildo? Zayna's sockdrawer?
Jamie: Si papi.
