Mutual combat

when two individuals intentionally and consensually engage in a fair fight

Originally added to courts so you wouldn't get a murder charge when engaging in a duel in the 1800s

Coke dealer: I challenge you to a duel

Drunk guy: mutual combat isn't even legal here, don't kick my ass

Supersonic Legend

The highest rank in rocket league. Rarely goes outside.

You: OMG! I finally hit Grand Champion! I'm officially the best player ever! I've spent years training for this. I can finally rest in peace.

Psyonix: Actually we've noticed a large skill gap within this rank and you're not actually good at this game until you're Supersonic Legend.
