Lady Di wave
A wave that’s so fake it could make a robot blush. You just twist your elbow like it’s doing the cha-cha and keep your palm cupped like you’re trying to catch a fart.
My cousin waved at me like she was trying to impress a goldfish.
He did the Lady Di wave so hard, I thought his arm was going to fall off.
She waved at me like I was the last piece of pizza and she was a hungry dog.
