lemon

The 🍋 lemon emoji officially represents the lemon fruit, but in digital slang, it often symbolizes "sourness" or "jealousy," stemming from the meme "lemon" or "feeling sour" when envious of others. It carries a bright, playful tone and is used to express light-hearted envy, self-deprecation, or humor, as well as contexts related to health, freshness, or acidity. On social media, it's commonly paired with phrases like "I'm feeling sour" to convey a teasing or ironic sentiment.
