"I was just thinkin'. About goldfish. Even though they are called 'goldfish' they aren't gold-colored, are they? They are red, right? The 'blue light' on traffic lights too, aren't they green? Things like that make me sick..."Have you ever noticed how sometimes, pickles are really salty? That's the sort of thing this article would be about if it were a Self-Demonstrating Article. But it isn't. That would be silly. In our everyday language we tend to use words that are representative of certain objects or characteristics. On the other hand, we have words or combinations of them whose real meaning has nothing to do with their name. These are known as misnomers. Mostly for historical reasons the misnomer sticks and nobody—or almost nobody—bats an eyelid when it is used, since it is well accepted and people know what it means; this particular variant is a common result of calling Smeerps "rabbits". A Cloudcuckoolander character and punster tropers are likely to hang a lampshade on these from time to time, complain that contents of the tin differ from the label (or that the tin itself is not made of tin), and that there's no baby in baby food. It may have resulted from an Artifact Title. If the name is itself an element of deliberate deception, it may be Doublespeak or a Super Fun Happy Thing of Doom. For series with nonindicative names, see Word Salad Title and Never Trust a Title. For songs, see Non-Appearing Title. Fluffy the Terrible, Deathbringer the Adorable, and Ironic Nickname are subtropes of this. Contrary to Exactly What It Says on the Tin. See In Name Only when this trope arguably applies to the title of a derivative work.
