Unc definition: what "Unc" means and examples

February 9, 2026

A nickname for an older male figure, often used to tease someone who is slightly out of touch.

Short for "Uncle," this isn't necessarily about a family relation. It’s used to point out when a man is acting "old," using outdated slang, or giving unsolicited "elder" advice. If your son calls you Unc, he’s likely teasing you about your age or your lack of knowledge regarding the latest internet trends.

Examples:

  1. "Alright unc, we know you used to be cool back in the nineties."
  2. "He’s only thirty, but he’s already got that unc energy."
  3. "Stop trying to use TikTok, unc, it doesn't suit you."
