bus tunneling 

a great game in which all of the people on a school bus put their backpacks in the center aisle to hide the floor (the surveilance camera can now not see the floor completely), and a person tries to get from one end of the bus to the other underneath the seats (or really any distance).
this activity can get you slammed with fines, juvy, or at least bus expulsion; only to be played under the lack of supervision of a substitute bus driver.only play when people who you know are above you, because people you do not know may try to kick you(it would suck nad you might get stuck)
i have personally played it and it's awesome.

guy1: hey, JC just went bus tunneling and got kicked by Ben!
guy2: what a dick, we gotta kill 'im!
Ben: it wasn't me, man, that dude did it!!
JC: let's get that dude!!!

Light tunneling 

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.

“Dawg this song has me light tunneling pretty hard right now.”
