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!
Idahomie: Thas why you gotta rock the Idaho Tall Boy fool.
A dent pushed into a beer can by your thumb while drinking. It should be unintentional, and is only a small thumb sized dent, not a partially crushed can. This adds a grip, helping you hold onto your beer when roundhouse drunk, a common Idaho occurance. Good for shitty drunks and kids with slippery hands.
You: I dropped my Pabst!
Idahomie: Rock that idaho grip next time fool.
