Rubby-dubby is British and Irish slang for fish chum (bait), and also a colloquial dismissive for nonsense. Not concerning, just regional vocabulary. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.
Rubby-dubby has two senses: (1) fish bait or chum used in sea fishing (British), and (2) a colloquial dismissive meaning nonsense or rubbish. Use the fishing sense in angling contexts; the nonsense sense in casual British conversation. Formal equivalents: "chum" (fishing), "nonsense" (general). Common non-native mistake: assuming a single meaning. Context disambiguates. Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.

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.
