While I found myself vaguely horrified...
...by this year's Oxford Dictionary words, I find this oddly heartwarming:
I mention all that ... because language. Because evolution. Because there is another way to use "because." Linguists are calling it the "prepositional-because." Or the "because-noun."
You probably know it better, however, as explanation by way of Internet—explanation that maximizes efficiency and irony in equal measure. I'm late because YouTube. You're reading this because procrastination. As the linguist Stan Carey delightfully sums it up: "'Because' has become a preposition, because grammar."
Because awesome.
