Well, if one expects every name for something to be a literal translation, then they will get irked frequently. Sure, comedians like George Carlin express anger, but they probably do it for comic value.
As for organic food, from wikipedia:
Meaning and origin of the term
In 1939, Lord Northbourne coined the term organic farming in his book Look to the Land (1940), out of his conception of "the farm as organism," to describe a holistic, ecologically-balanced approach to farming—in contrast to what he called chemical farming, which relied on "imported fertility" and "cannot be self-sufficient nor an organic whole."[3] This is different from the scientific use of the term "organic," to refer to a class of molecules that contain carbon, especially those involved in the chemistry of life.
In the end I guess it doesn't matter in most cases. I mean when someone calls a car a 'hot rod', they don't literally mean that it is a burning hot lead pipe with wheels, or when I say something is cool, I don't mean that it has a significantly lower than average temperature.
Some things are over the top though.
Like the obsession people have with the prefix "pre", when it doesn't apply... or how every product now has some HD label, even when it doesn't make sense in the least.
