Pubes and cock
A pair of shorts with a malfunctioning zipper that can only be held up by a belt or drawstring. The zipper is usually zipped up only to shortly go back down, revealing the contents intended to be covered by a functioning zipper, often this is pubes, cock, or both.
Blake: Hey Eddie, can I borrow a pair of shorts?

Eddie: Yeah, but all I got are those fucking pubes and cock.

Blake: Fuck that, I don't want my little cock to pop out in front of all those girls.
