There's a young woman with a youtube channel I watch sometimes. Now, she's clearly targetting a younger audience, and her talk is peppered with all the current fashionable slang, and sometimes I literally have no idea what she means by some apparently widely-known expression or turn of phrase. I have to remind myself that when I was young, our talk was full of hippie, biker, and ghetto argot, all mixed together, so maybe our elders were equally bemused. However, my suspicion is that the good ol' internet has exaggerated this phenomenon, as so many others.
