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.
