When someone sends that squiggly smiley face, it often means they're rolling their eyes with a wink, like they're in on the joke but not taking it too seriously

In certain social circles, especially online, the wiggly emoji is shorthand for a playful jab, like saying 'you're being ridiculous but I like it

At work, typing that face sometimes means you're softening a critique, letting someone know you're laughing along with them to keep the mood light

Among couples, it can be a way to flirt without being forward, like a wink that says 'I see what you did there, and I approve

For younger folks, especially on apps like TikTok, the face is a way to show they're in on the absurdity, like saying 'we get how silly this is and that's exactly why it works
