With sales of over one million in its first year, Nintendo's Wii (pronounced 'We') is the fastest selling game console so far in the UK, not least because of its wireless controller (known as the Wii Remote), which can be used as a pointing device and can - thanks to its accelerometers and infrared detectors - sense its own position in 3-D space, allowing gamers to jump around their rooms, doing things like whacking 'balls' back at the screen. While not encouraging users to venture out to their local park or tennis court, (and, some fear, discouraging them from doing so, if they were ever interested), it at least gets them off their arses and doing some 'exergaming'.

Consequently, people with toned, fit bodies (particularly if they're known to be Wii gamers) are often said to have 'Wii waists', 'Wii thighs', 'Wii tits' and/or 'Wii pecs'. They're judged to be 'Wii trim', 'Wii taut', 'Wii hot', or plain 'Wii fit'.

Wii Fit is also the name of a Wii program (due out in 2008) which, with the use of a wireless 'Wii balance board' that looks like wide bathroom scales, with a pad for each foot, will engage users in press-ups, snowboarding and assorted other 'indoor exercises', while measuring their weight, body mass index, centre of gravity, stamina and 'Wii fitness age', comparing players' physiques and fitnesses competitively.

Households in 2008 will thus resound with more and more phrases such as 'You've been sneaking upstairs for a Wii and not telling me, haven't you darling?', 'I may never get out in the fresh air, Mum, but I'm Wii fit as a fiddle,' and 'If only we could afford three more balance boards we could all go jogging together.'
