Gaff is British and Irish slang for home or house. "Come back to my gaff" means come to my place. Not concerning, just informal vocabulary. Has nothing to do with the old sense of a fishing hook or theatre slang. 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.

British / Irish slang for one's home or apartment. "Round at my gaff" = at my place. Slightly blokey register — you'd say it to mates, not your manager. Common in London, Manchester, and Dublin.
"Come round to my gaff later?"
Origin: Likely from Romani / Traveller cant, entered British English in the 19th century, originally meaning a cheap public hall or fair. Morphed into "home" by the 1930s.

For ESL learners
Gaff in British, Irish, and Australian English is informal slang for a person's home, especially among younger speakers. Use in casual British English contexts. Formal equivalents: "home," "flat," "place." Common non-native mistake: confusing with the standard senses of gaff (a long pole with a hook, a stage error, or US slang for nonsense). The home sense is dominant in current British informal speech.

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.

- sus gaff78%
A gaff — a home, flat, or situation — that gives off deeply suspicious energy. A sus gaff is the kind of place where you arrive and immediately feel something is off: the vibe is weird, the host is acting cagey, and you're not sure you should have come. It might be a party where you don't know half the people and the other half are acting sketchy. It might be a flat that just feels wrong somehow — too quiet, curtains always drawn. Sus gaff is the slang for when your gut says leave early.
- gaff god76%
Someone whose home is so impressively set up — in terms of size, interior design, vibe, or all three — that it has achieved mythological status among their social circle. A gaff god doesn't just have a nice place; they have the place: the one everyone wants to be at, the one that shows up in group chats as the default venue, the one people remember years later. The title applies equally to a genuinely premium apartment and to a legendary student house where every wall tells a story. What matters is that the gaff has gravitational pull.
- gaff core74%
A vibe or aesthetic built entirely around someone's gaff — their flat, house, or bedroom. Gaff core captures that lived-in, thrown-together home energy where mismatched furniture, fairy lights, and takeaway boxes somehow form a coherent identity. It's the aesthetic of making do and making it yours, celebrated rather than hidden. If your gaff has character, if guests walk in and immediately get it, you're operating in full gaff core territory. The opposite of a staged, Airbnb-ready space.
- gaff energy73%
The specific atmosphere, vibe, or feeling projected by someone's home — their gaff. Gaff energy is real and immediately readable. Some gaffs have cosy, low-key energy: soft lighting, blankets everywhere, you're asleep within twenty minutes. Others have chaotic gaff energy: mismatched everything, always something going on, people turning up unannounced. You can also use it to describe the general aura someone carries from their living situation bleeding into their personality. If you've got gaff energy, your home has shaped you.
