“Tall Cool One”. This refers to a tall, cool, brewski. Usually contained in a vessel of elevated proportions. The standard 12 ounce longneck glass bottles, the 16 ounce Tall Boys cans, and the 24 ounce Tall Boyz cans all apply to this title. “Tall Cool One” has been forever immortalized by the late Chris Farley in the hit 1996 comedy Black Sheep. See quote below.
