Point of Order Mr Speaker: Definition 1. A âcommercial atâ is the symbolâ@â; also called an 'at symbol', an 'at sign', or just 'at', and sometimes mistakenly called an [[ampersand]] (''&'' is the ampersand). It is a cursive form of 'Ä,' or 'Ã ,' a term of debated origin. Therefore, @ is equal to âatâ Definition 2. Twat n. Taboo sl 1. the female genitals 2. a foolish person [from ?] So when you call someone a Tw@t, you are in fact spelling it incorrectly as Twatt. In fact I donât believe that the word âTwatâ is a swearword at all, so when someone is acting a twat or being a twat, why not just call him a twat. If deemed to be the aforementioned swearword then the correct spelling is âTw@â. Yours sincerely, Mr Pedantic Sits back, breathes out and waits to be called a twat!
