A pair of Pants (British) / Briefs / Underwear, that are missing one or more of the front fastening buttons.
Allowing for one's penis to 'escape' the underwear in a style akin to the late Harry Houdini.
All my boxers are in the wash other than my these damn Houdini Pants, my cock keeps falling out every time I walk anywhere.
