A tunnel in which you see when being high with weed laced with coke. You stare at a star with your boyfriend and or friend for at least 10 minutes.

When smoking weed one calls back door and after the person loading the bowl takes his/her first hit the person who calls back door gets next hit, and the rotation goes from there.
Person 1: I call back door.
Person 2: No I already called back door when we were in the car. :
Person 1: Awww fuck.
