Snooki
Definition
A nickname for Nicole Elizabeth Polizzi, an American television personality, author, and entrepreneur, best known as 'Snooki' from MTV's reality series Jersey Shore (2009–2012), where she embodied the pint-sized party girl archetype with her signature pouf hairstyle, tanning obsession, and fist-pumping antics.
Informally, to act in an over-the-top, trashy-fun Jersey Shore style—think meatball energy, excessive tanning, and unfiltered chaos.
Examples
