No idea what the context of this street brawl is but everyone in this neighborhood knows not to mess with Grandma now.
Three dudes and two women begin to tussle as the three guys start to fight each other. The younger woman begins to grab and tug on one of the dude's arms and Grannie isn't having any of it. Grandma comes up from behind and applies a textbook sleeper hold to her younger counterpart and within four seconds, she's unconscious lying on the concrete.
I have a feeling this Grandma has had to perform this maneuver on someone else judging by how effect she took that lady down. Good for her.
