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.

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.
