An absolutely legendary phrase. You know what it means. Can be used in tandem with “3 4 McGregor" for extra emphasis.
Alexa: Dude I hit ‘em with the 1 2 Mayweather!
Josephina: Damn that’s tiiiiiight!
Maddi: What the hell is a 1 2 Mayweather? You guys sound stupid.
Eva: C’mon, you should know by now. It’s the 1 2 Mayweather, and it’s the greatest. *Mic Drop*
