Indeed. But still not correct
The reason it's a headache is that the world of anime has turned the term into a kind of slang word, but without considering it slang. It's correct without people knowing that it's actually incorrect, just a "saying".
It's as if people suddenly thought that "brotha" or I don't know, any slang, was a correct word.
