The Wingman Technique usually involves (and is best preformed with only one) friend accompanying another to a club or other social setting. If one friend finds a hot girl who is accompanied by an ugly friend (i.e. grenade), it is the sworn job and duty of the accompanying friend (the wingman) to occupy the ugly girl so his friend can get action with the hot girl. The revered duty and purpose of a wingman is to streamline the night for his friend as much as possible, tackling any obstacles and cockblocks.
