Low key grimy describes someone who presents as chill and trustworthy on the surface but quietly moves in sneaky, dishonest ways when no one's watching. They never make loud declarations of shadiness — they just slowly, subtly do you dirty. It's the passive-aggressive cousin of full grimy energy: the person who'll steal your client, slide into your DMs behind your back, or undercut you at work while smiling to your face. The 'low key' signals it's easy to miss until the damage is already done.
He never comes off wrong in public but he's low key grimy — always working an angle you don't see coming.
