Fabby is a casual British slang intensifier meaning fabulous, great, or excellent. It's a cheerful, slightly effusive word — the kind you'd hear from an enthusiastic friend rather than in formal speech. Its register is informal, warm, and upbeat, often used to express genuine delight or approval. Particularly associated with British regional speech, especially in the north of England, it carries a slightly retro, good-natured energy. Think of it as a more playful cousin to 'fab', itself short for 'fabulous'.

She came back from the salon looking absolutely fabby — best haircut she'd had in years.
Origin: Diminutive/playful extension of 'fab', itself a clipping of 'fabulous', which derives from Latin 'fabulosus' (celebrated in fable). The '-by' suffix adds a cheery informal quality common in British slang. Editorial expansion authored on Slangora.

It's a cheerful, slightly effusive word - the kind you'd hear from an enthusiastic friend rather than in formal. It is informal slang, fine in casual speech but not suited to formal contexts. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. As a place or proper-name reference it is purely descriptive.

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.
