Engine Underpants

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.

*Insert mental image of Thomas the Tank Engine Boxer-Briefs >>Here<< .*

Underpants

Usually a term used by 4 - 10 year olds to describe their underwear. This word is often used by Hipsters because it's incredible ironic and non mainstream. A lot of hipsters are turning to under pants because of their nostalgic feel, it reminds them of their past.

Hipster says: Yo dude check my underpants
Non hipster says: Faggot

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.
