A term used to describe a fighting style or technic. To take one's opponent to the ground, establish a dominant position. Usually a top position(i.e., mount, side mount, half mount, etc. can also be used while in one's "guard"). Then reign down punches, elbows and forearm strikes to the downed fighter. This is used in MMA (Mixed Martial Arts) or any other NHB (no holds barred) fight.
