Be wary what you disparage, you may coin its name.
Impressionism got it's name from a Monet painting called "Impressions of a Garden". A detractor (and there were many at the time) proclaimed that that's all these paintings were, simply impressions. Thus, a entire genre was born from a single name.
The Big Bang (aka: The Horrendous Space Kablooie) was initially denounced by a detractor (and there were many at the time) as being implausible. How could the whole universe erupt from some "big bang"?
Gothic Architecture was derided thoroughly since it departed from classical forms. Its detractors (and there were many at the time) said that the whole group of buildings built in this style were barbaric in their ignorance of traditional shapes and forms. In fact, they looked like something the Goths would build.
