😁 · Smileys & Emotion › Smiling faces · Emoji 0.6 (2010)
😁 is a face grinning with its teeth together and happy, squinting eyes.
It's a big beaming smile: proud, excited, pleased with yourself. Some people read the bared teeth as a little cheeky or awkward, more 'heh' than pure joy, so it also works when you're owning up to something.
