Seen in both Family Guy and stoner parties, brick walling is the act of getting a person to mentally visualize a hallway with many corridors, and then tricking them into running into a visualized brick wall at the end of said hallway.
Person1: You think he's high?
Person2: Let's find out. Hey druggy. Imagine you're in a hallway.
Druggy: (blank stare)
Person2: You start walking. You take a right. Then another right, then a left. BRICK WALL!
Person2: Yeah, he's tweaked.
