An Idaho Tall Boy is made by holding two regular, 12oz beers, in one hand stacked on top of each other. the two regualr beers form a tall boy, 24oz. Better than double fisting, the Idaho Tall Boy allows you to still hold two beers, but leaves a free hand to smoke or punch with.
You: I can't punch this dood! My little hands are full of beers!
