Perguntas sobre exemplo de orações com, e a definição e o uso de "Awesomest"

A: The most awesome

A: None of them are correct. You can't add -est to "awesome."
The correct way is "One of the most awesome days."
Using "those" or "these" is wrong because it is referring to a set of other days, when you are talking about one day (to call out the best day of them all).

One example of a correct usage of "those" is "I'm having one of those days," meaning your day isn't going well. The "those days" here refers to terrible days we can all imagine, and compares today to it.
I suppose you could do the opposite here and say "I'm having one of those awesome days where everything is going just right," but that isn't using the superlative form.

A: it's slang
awesomest -not proper grammatically
