Wiki: The word meat comes from the Old English word mete, which referred to food in general. The term is related to mad in Danish, mat in Swedish and Norwegian, and matur in Icelandic and Faroese, which also mean 'food'. The word mete also exists in Old Frisian (and to a lesser extent, modern West Frisian) to denote important food, differentiating it from swiets (sweets) and dierfied (animal feed).
If you want a burger, go eat a freaking slaughtered cow patty burger, don't be all fancy with that highly process crap.
