Things like: eye gouging, fish hooking, head butting, hair pulling, face shredding, palm heel strikes, ripping off an ear, biting, pinching, finger locks to pull off a choke or lock, strikes to the middle of the throat, neck cranks/breaks, kicking and stomping a person who’s down, joint and limb destruction, groin strikes, knees and elbows to a persons spine, knee destruction, throwing people so they land on their head or face down, etc. Several of these things WILL END the grappling game fairly quick, if you have enough speed and skill to pull-them-off.
