The definition of 'toxic masculinity' as a concept that you have presented doesn't exactly match with my previous understanding, but still does not mesh well with Elliot Rogers. Or at least, if it does, then it only does so because of the sections of the definition that match up with standard asexual narcissism.
For instance, there really isn't much evidence that Elliot Rogers craved danger or shunned responsibility or commitment any more or less than any other male his age. Certainly he approached women with sex as the end, and only, goal - but again that isn't particularly abnormal for a male his age. He definitely did objectify women, but he also objectified men - as an element typical to narcissism, he was the star of his own movie. Everyone else was a background character that existed to facilitate the his goals and desires. Delusions of grandeur aren't necessary for this brand of narcissism, but he had those in spades anyway.
I have to disagree that he doesn't fit the bill. Those are all examples of toxic masculinity, I don't think one needs to encompass them all in order to use the term to describe them. Looking at the small quote I pulled from geek feminism, it reads "...socially-constructed attitudes that describe the masculine gender role as violent, unemotional, sexually aggressive, and so forth." It doesn't say one needs to exhibit all of those qualities, only that all of those socially constructed attitudes fall under that umbrella.
Ultimately it was the repeated rejection that shattered the illusion of his 'movie'.
Did you ever read his 'manifesto'? I read it from front to back. I think I remember a single case of him actually being rejected, and he threw a drink at the woman. Most of what he considered 'rejection' was nothing of the sort. Women not throwing themselves at him wasn't rejection. I would say the perception of rejection would be a more accurate statement.
On that basis I assert that although the women took the brunt of his anger, it was not the women that he was angry at - it was the realization that he was not the most important/only character in the story. It could have just as easily been the basketball team that became the focus of his anger, should they have repeatedly turned him away. And related to that is why I refer to him as a 'misanthrope' rather than a 'misogynist and a misandrist' - he hated everyone for the same reason, although in practice the anger focused and manifested in different ways - they all failed to play their parts properly.
While I agree that he hated a lot of people, and in different ways, I didn't see the level of self awareness in his manifesto where there was ever any sort of realization that he wasn't the most important person.
A short google search of Elliot Rodger toxic masculinity (I was misspelling his name before) turned up quite a bit.

I think it's pretty important not to just dismiss what E.R. did as a product of mental illness. I think it's doubly harmful because it not only further stigmatizes mental illness and marginalizes the mentally ill, but it creates this 'other' to cast blame on. It removes the need to look at how harmful attitudes that everyday 'normal' people hold that could lead to the same thing, and instead just sweep it under the rug as actions only 'mentally ill' people could commit.
