A bizarre body-shaming trend has exploded in social media from the same social network who brought us the Belly Button Challenge – a bogus way to self-assess your weight.

The more you can stack without them falling over, the more “attractive” you are, apparently.

Although the challenge is – obviously – ridiculous, it fuels real insecurities and can be dangerous according to experts.
