For ESL learners
"OFEX" means: A facility used for trading in stocks that are not quoted on any London stock exchange.. Register: neutral, standard English, usable in most everyday contexts. Note the regional or dialect label (British) — usage may sound odd outside that variety. 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.

- oofless57%
(UK, slang) Short of money; poor.
- offy57%
A British and Irish informal term for an off-licence -- a shop licensed to sell alcohol for consumption off the premises (as opposed to a bar or pub). The British/Irish sense is the most broadly known. In Australian cricket slang, 'offy' separately refers to an off-break bowler or delivery. The word is an excellent example of a short informal form that carries entirely different meanings in different contexts.
- oofless57%
British slang, now mostly historical, meaning flat broke, skint, or seriously short of cash. If you're oofless, your wallet is empty and your bank account is painful to look at. The word derives from 'oof', which was Victorian-era slang for money. Being oofless was the natural opposite — having none of the stuff. While the term has faded from everyday use, it's a colourful piece of old London English with a pleasing ring to it.
- stockjobbery56%
A British trading term for the business or practices of a stockjobber — historically a market maker on the London Stock Exchange who traded shares on their own account rather than on behalf of clients. Stockjobbery carries a faint whiff of disrepute, implying sharp dealing, speculation, and the kind of financial maneuvering that polite society frowned upon. The role of stockjobber was formally abolished when London's 'Big Bang' deregulation in 1986 merged the functions of jobbers and brokers.
