When a jacked guy is wearing a tight shirt, then subtly stretches out his arm. He makes it look nonchalant but the main objective is to raise the sleeves and show more bicep, without looking like a d-bag. This can also be performed with both arms at the same time, which is appropriately called a "double tuck". The worst tuckers will still perform the action when wearing a tank top. They will also find subtle ways to tuck their sleeves up, for example when reaching for their drink, or taking a cigarette out of the pack.
