What it means
Muggy describes a sly, disrespectful move, or a person doing it, like they’re trying to embarrass you or treat you like a mug. You’ll hear it in lines like don’t mug me off or that’s well muggy. It got extra airtime on Love Island, but it was already standard London chat. Basically, if it feels shady, it’s muggy.
Usage examples
"Man slid into my girl’s DMs while I’m sat right there, then acted innocent. That’s proper muggy, I’m not having it."
"That was a proper muggy move, eating my chips while I was in the loo and acting like nothing happened."
Where it comes from
In multicultural London English muggy has nothing to do with the weather: it comes from mug, the fool you make of someone, so a muggy move is a sly, disrespectful one and a muggy person is the one pulling it. Acting muggy means treating someone like a mug. Pure London playground and road slang.
