I've noticed an interesting usage where "because [noun]." is used at the end of a sentence to mean "because [...everything that word implies. Nothing more needs to be said]". It often has a wry or sarcastic tone that implies the subject considers the word to be a blanket explanation for something.
An example might be "She couldn't drag herself away from the computer because internet.", the implication being that the Internet is seductive. Another example is here where "because sex" is used to imply that a group of people have a simplistic attitude to how sex affects people's lives.
The odd grammar causes a clang in my head when I read it, but of course that is the point; the author is showing how this word will stop the conversation dead in its tracks, so it is quite effective.
Is this a new or emerging usage, or have I just started noticing it?
