The wall that your
bed is pushed up against. The
booger wall is not the entire wall, but just the section of wall that begins even with your head and runs along the edge of your matress to about mid-thigh, or as far as you can reach toward the foot end of your
bed. This length of wall extends from the top edge of your mattress down the wall approx 4 inches. Boogers are picked while lying in bed and wiped in this area.
