I suppose we are all familiar with the trade names which have entered the language as words, such as "xerox" for "photocopier", "kleenex" for "disposable tissue", "coke" for "cola-flavored soda", "kotex" for "sanitary napkin", "vaseline" for "petroleum jelly", et. al. What happens here, of course, is that a manufacturer dreams up a short, snappy name for his product. The product then becomes such a great hit that people use the trade name to denote the product, much to the chagrin of competitors, and after a while, the name goes into dictionaries as a word. What is strange, or stranger, is how manufacturers come up with these names in the first place. Some years ago the Standard Oil co. which produced gasoline under the name "Esso" (short for Standard Oil) decided its image was too old and stuffy, so they decided to change the name and came up with Exxon. There was a lot of criticism at the time because the new name meant absolutely nothing and looked funny with the 2 x's. They kept that for years and it's still around, although I don't see that it ever helped their sales. It seems marketing experts are still at it, dreaming up names which are designed mostly to catch the eye; they don't have to have any meaning whatever.
