When two people fight and one of them ends the fight in a two hit combo. Occasionally followed by the 3 4 McGregor.

2.I’m about to hit you with the 1 2 Mayweather.

Mayweathered 

When things happen without being prepared for it; not looking; not paying attention; didn't see it coming.

Always keep an eye, you don't wanna get mayweathered just like Ortiz!

1 2 Mayweather 

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*

mayweathered 

If you experience something in life that is a staggering disappointment and severely underwhelming even though there was an excessive promise of greatness, you've been mayweathered.

Bob: I went to the greatest steak restaurant in the history of man and spent $3000.00 on an overcooked and dry steak!
Joe: Dude, you got mayweathered!

Mayweathering

Another term for hugging again and again and again

Me: Yow long time no see
You: *hugs*
Me: *hugs too then let go*
You: *hugs again*
Me: What's the matter with you? Stop mayweathering me.
