When you stick a straw in you butthole and connect it someone else's butthole and then fart in it so it goes from your butt to the other person's butt. It is a rare form or intimacy that only the most passionate of lovers (or even friends) dare to try.
She wouldn't believe that I loved her until we tried the fart tunnel. Now we're happily married with two kids.

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.

Light tunneling (or simply “going down a light tunnel”) is when you’re so baked that an especially great song or food makes you trip 10 times harder. This increase in highness generally produces very sharp visual effects/focus, and can take your imaginative abilities higher than ever thought possible. Many people when light tunneling will unintentionally create movies in their heads that go along with the song, food, or experience, and can sometimes even cause people to picture themselves flying down “the light tunnel”. The experience can be so intense that it can be hard to recall the next day, but regardless of what end of the tunnel you experience, it’s name comes from the especially vibrant tunnel vision you recieve when entranced by said song or food.
