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.

Undercity

Undercity is also another explorable area from another mmorpg game, Guild Wars:Factions. The area is connected to the region of Kaineng City.

"Cantha is a nation of many, many people. The marketplaces are packed, the cities are overcrowded, and the sewers are overflowing with waste. Underneath the busy streets, the darker side of Cantha rears its ugly head. If you're looking to engage in unsavory activities, Undercity would be the place to come."

Silly in the Underpants

State of being in absolute "pimpish" synergy. Mind, body, and underpants coming together in an ultimate state of carma leading to divine intervention and infallability. Most often associated in situations dealing with the opposite sex.

Iceman: Dude, did you see the funbags on that dime piece?

Johnny: I am so silly in the underpants Ice. Permission for fly by.
