An "omoplata" is a technique in Brazilian Jiu-Jitsu where you lock an opponent's shoulder with your legs and body, while the opponent is lying face down and you are sitting up next to them, so as to internally rotate their shoulder. The word omoplata refers to a shoulder-blade or scapula in Portuguese. The suffix "-plata" has evolved into slang in Brazilian Jiu-Jitsu that appears in the name of other techniques such as the "gogoplata".l
