gentleman's fight
A civil, humane fist-fight organized between two individuals for the purpose of settling a dispute. Usually organized by a third party who is neutral to the situation. These very rarely occur in reality because there is almost nothing civil, humane, or organized about punching someone in the face.
Adam: "Hey Greg, it looks like Morgan's boyfriend heard you talking shit about him. He's pretty pissed. If you'd like, I can organize a gentleman's fight between you two."
Greg: "What the fuck did you just say? A gentleman's what? I think you've had enough cocaine tonight, Adam."
