"one-and-done" means: A basketball player who plays college basketball for a single year and then declares for the NBA draft.. This is informal slang, common in casual speech, texting and social media, but not appropriate for school work, applications or professional settings. There is no real cause for concern in itself; it is everyday peer vocabulary. If your child uses it, a light comment about audience and register is usually enough — no need to escalate. Context, more than the word, tells you whether to follow up.

Ohh that's very interesting :0 It does make a lot of sense that the skin would be more sensitive! Also very interesting that the standard is to shave twice - I thought it was a one-and-done thing
Don't quote me on it, but I don't think there's even any unique materials in there either so you'll pretty much never have to come back unless you want.. I think a bunch of coal? Either way, it's one-and-done!

"one-and-done" means: A basketball player who plays college basketball for a single year and then declares for the NBA draft.. Register: informal slang, fine in casual conversation, texting and social media but not in academic essays, business writing or formal speech. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.

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.
