I am looking for one word to describe making a mistake that ordinarily should have been well within your ability to perform properly.
For example, if someone is considered especially gifted in perceptual organization, yet they fail to notice how to open an extremely simple lock, what type of mistake is that?
The connotation I'm looking for is something like a gross blunder, or an uncharacteristically stupid mistake.
The one word can be any type of word, i.e. noun, adjective, verb, etc. For example:
- "You have made a (noun)."
- "You just (verb)ed."
- "That was very (adjective)."
Words like "gaffe", "blunder", "mistake", to me at least, don't indicate the extreme uncharacteristicness of the stupidity involved.
