Underground tunnels made to deliver heat (in the form of steam) from a central heating plant to multiple buildings. Commonly found on college campuses. Often retrofitted with wires to deliver electricity or telecommunications. Sometimes used by students or other adventurers for recreational purposes, see urban exploration.
We found an open hatch that led into the steam tunnels, and spent a few hours exploring the campus from underground.

When your buddy drops trow outside during the cold winter months, presses his butt cheeks against the door window and farts. The creation is called a Steam Angel.
My buddy Jake was outside smoking and tapped on the window. When I turned around, all I saw was his bare ass as he farted and the window frosted over with his steam angel.

This is when you take 2 maybe even 3 packs of pudding depending on how hungry you are, lean back and pour the pudding inside your asshole. Then you let it sit there for about 4-6 minutes so it gets just the right taste(shouldnt shit for a couple of days) and then you let the person who wants it eat it out of your asshole.
