This would be an example of "absolutes." Using an absolute will usually make your sentence incorrect; "never" and "always" are rarely true. When writing something formal--essays, news, research papers--you should try not to use absolutes.

While absolutes shouldn't be used for formal writings, English speakers will very often use them in casual settings. I itallicized some spots where I could have used absolutes, and if you replace those words with "never" or "always", I think you'll understand what I'm saying better.

This is an absolute or hypberbole, but most native speakers will understand what the author meant by that.
