Term coined by psychologist Corinne Sweet, in response to a Travelodge survey which found that a quarter of Britons lie about their weekend activities to impress others. Envyous that other people are having more fun than them, while a weekend may consist of catching up on paperwork and being lazy, lies are told of extreme activities and derring do.
Anne: Blimey o'riley, did you hear what the MD's secretary was up to at the weekend? She's got it made!
Jemima: No, she's talking out of her arse, she's known for her weekendvy; she goes all Pinnochio every Monday morning.
