Brazilian jiu-jitsu
Brazilian jiu-jitsu (Portuguese: jiu-jitsu brasileiro [ʒiw ˈʒitsu bɾaziˈlejɾu, ʒu -]), commonly abbreviated as BJJ, is a self-defense system, martial art, and combat sport based on grappling, ground fighting, and submission holds. It is primarily a ground-based fighting style and involves taking one's opponent down to the ground, gaining a dominant position, and then using a number of techniques to force them into submission such as joint locks, chokeholds, or compression locks.
