Sideboob
The origins of the sideboob – the area between armpit and ribcage – are not officially recorded, but it is thought to date back as far as 2005 to an episode of Family Guy, with Peter Griffin presenting his Sideboob Hour: "
Underboob
The bottom part of the breasts, exposed by an ill-fitting top – perhaps a jumper that looks like it has been unravelled from the bottom up. According to Urban Dictionary, there is even such a thing as an "underboob shirt". The underboob is not exactly new – think of those cliched 1980s shots of women in chilly crop tops – but it is enjoying a renaissance.
Back dimples
Also known as dimples of Venus, these are the little indentations some people have either side of their lower back (they're genetic).
Side butt
"Side butt is the new side boob," proclaimed New York magazine earlier this year, using an array of pictures of celebrities, including Kate Winslet and Jennifer Lopez, to prove it, all wearing dresses with transparent panels to display varying amounts of flesh between the top of the (side) thigh and hip, and around to the buttocks.
Thigh gap
The deranged idea that when you stand with your feet together, there should be a visible gap where your upper inner thighs do not meet, has apparently become the new obsession.
Bum slip
The bum slip is, apparently, the fleshy underside of the buttock cheeks, made visible when wearing very short shorts (Miley Cyrus), or a kind of leotard (Kate Moss). It is also known as "underbutt".
Butt cleavage
Already known as the "builder's bum", but now, thanks to Heidi Klum among others, the exposed arse crack has been legitimised as fashionable. At last, a body trend everybody – man and woman – can join in with.
