Adidas isn't an acronym for "All Day I Dream About Soccer."

If you, like me, thought Adidas stood for "All Day I Dream About Soccer," you're wrong. It turns out the athletics-apparel brand is named after its founder, Adolf Dassler, who started making sport shoes when he came back from serving in World War I, according to the LA Times. The name combines his nickname, Adi, and the first three letters of his last name.
