Backyard Grappling Match Ends with Sore Loser Rage

A backyard friendly fight turns serious fast. The BJJ practitioner in the grey shirt shoots a clean double leg takedown on his shirtless opponent. Both hit the grass hard. The untrained fighter immediately wraps a guillotine around his opponent's head from bottom position. But the grey shirt grappler stays calm. He's already in side control and knows the guillotine won't work from there. A Von Flue choke is available but he doesn't take it.

The shirtless fighter manages to recover half guard briefly before letting it go under pressure. The BJJ guy steps over to full mount and frames on his opponent's face to break the guillotine grip. The shirtless fighter makes a critical mistake by extending his arms. The grey shirt instantly capitalizes, traps the arm, and falls back into an armbar. His opponent tries to stack and escape but gets redirected into a belly-down armbar position.

The crowd watches nervously. Someone yells about hand positions being illegal like this is a wrestling match. The BJJ practitioner controls the armbar but doesn't crank it hard. Then something snaps in the shirtless fighter's mind. He explodes up screaming like a wild animal. The friends rush in to separate them. The friendly bout just became something else entirely.

Did the shirtless fighter tap before the rage? Will the BJJ guy's restraint prevent a serious injury or provoke round two?
