One of the most common ways to insult someone is to tell them to “eat crap”. It makes sense to use that expression as an insult, after all, what could be less appealing than a mouth full of human excrement? Thanks to Japanese scientist Mitsuyuki Ikeda, eating crap may become a dietary choice rather than an insult in the near future. Ikeda has developed a meat alternative made of soya, steak sauce extract, and protein extracted from human feces. If you want to go vegan, but you don’t like soy burgers, the poo burger offers an alternative. Or you could just keep eating meat instead of eating crap.
