For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

Unc mode hits when a person starts complaining about music being too loud, recommending movies from 2003, or showing up to a party wearing New Balance dad sneakers unironically. It's not just aging — it's a specific behavioral frequency that younger people immediately clock. Can be affectionate or a gentle roast depending on delivery.
