The largest fast-food chain in the world (and for a reason, quit bitching about how their food is "piss poor"). Theyve got some pretty good food (fries, nuggets, etc), but most of it is unhealthy and eating too much of it will eventually make you fat. As a result, McDonalds is frequently bashed/sued by fat fucks who are too inept to keep themselves on a healthy diet.
Also targetted by communist hippies because its a big corporation, and big corporations will eat your soul.
And they've got a shitty marketing campaign (Im lovin it: that sounds gay)
