Engine Underpants / ˈɛn dʒən • ˈʌn dərˌpænts /

Also known as " Creepers / ˈkri pərz / "

Any type of undergarment with a tendency to repetitively ride up your butt crack, with the power and reliability the of a steam-engine train riding the rail to the express tunnel, leaving you unhappily maneuvering it free and/or pulling it out like clockwork.

That is a broad definition. Depending upon circumstances, the specific meaning could be anything from shaking hands with the unemployed, to cheating on your partner, to incest.

Not with your sister, you jerk! That's underwarez!

Don't stick your hand in your underwarez in public!

Stop shopping at the middle school, there's nothing there but underwarez!

Philadelphia Underpass

When Gentleman Number 1 is getting railed up the ass by Gentleman Number 2. At some point, Gentleman Number 1 reaches under himself and sticks a finger up Gentleman Number 2's anus, thereby giving him the ol' Philadelphia Underpass.

When Craig gives me the Philadelphia Underpass, his finger smells like my ass all afternoon.
