The Tunnel is how Coloradoans refer to the Eisenhower Tunnel, the highest vehicular tunnel in the world. It carries I-70 through the Continental Divide and through to the killer powder on the other side.

Usually used when talking about how long it's going to be until you shred the gnar.
"How long til we get to Vail, man? I can't wait to rip with my new board."

"At least an hour, we're not even to The Tunnel yet. Better light that blunt now."

"Dude, i havent stopped shitting blood since I tunneled that blunt."" "Yeah, that was awesome."

The Tunnel is a very large and rounded entrance located around the pelvis. Many things enter, but none come out. Never go near the Tunnel.

Stretched ear piercings.
The holes are stretched with larger and larger plugs. When you gradate to a big enough plug, it can have a hole in it and you can see to the other side, tunnels.
"Man your tunnels make me hot in my dirty places. I hope you never get a brain and realize that limp hoops of skin attached to your head are idiotic."
