submission hold
In combat sports, a submission hold is a grappling hold that is applied with the purpose of forcing an opponent to submit out of either extreme pain or fear of injury.
Submission holds are used primarily in ground fighting and can be separated into constrictions (chokeholds, compression locks, suffocation locks) and manipulations (joint locks, leverages, pain compliance holds). When used, these techniques may cause dislocation, torn ligaments, bone fractures, unconsciousness, or even death.
