The 'Zesty' slang meme refers to behavior that is flamboyant, energetic, or 'sus,' often used playfully to describe someone acting with unexpected sass. Originally a culinary term for sharp flavor, it evolved on platforms like TikTok and Instagram as a way to label certain poses, dances, or personality traits. The meme gained momentum as users began documenting 'zesty' behavior in everyday life, turning it into a widespread cultural shorthand for being extra or feminine. Today, it is used across social media to highlight comedic moments of high-octane personality or to jokingly question someone's mannerisms in a lighthearted, meme-centric way.
