I hate to mention the C-word when it is everywhere else and this website is a refuge from it, but this got me thinking.
A newspaper website headline said that "Thousands of people flaunted coronavirus distancing rules".
Unless they're showing off how virtuous they are, I think the word intended is "flouted". Someone called this a grammatical error, and what I'm really think about is whether using a wrong word which is similar to the intended one a matter of grammar. A malapropism perhaps?
