Language is fluid and ultimately the correctness of grammar is exclusively bound in whether ideas are communicated successfully.
Also, people who know what you are saying but feel compelled to complain because it doesn't line up with what they have learned or feel is the correct way to write or talk are basically the worst.
I have no problem with the grammar of it, I just think it sounds rubbish. "A whole nother." Clumsy. There's something a bit Idiocracy about it.It's one of those irritating vocal tics that get out there sometimes, like when people make a statement as though they're asking a question?
