When you grab a stolen object from someone and use the same momentum to elbow them in the face, simultaneously knocking them out and reclaiming your property.
Eric Sparrow: What do you say? One last trip around the neighborhood. Winner takes the tape.
Steve: elbows Eric and grabs the stolen tape
Stacy Peralta: Holy shit, you just jaw jacked Eric!
Angrily struck by another human being . Not a light tap
The man did not heed the warning And he got a jacked jaw by Shawn
A person or people on drugs that are talking just to hear themselves talk
Holy crap that person is Hook Nose Wambat Jack Jaw I didn't think she was ever going to shut up!
