Who is Lil' Tasty and what is Luber?

Haha, where did this girl/character come from? Right now, these videos aren't quite hitting viral status yet, but in a few days' time I could totally see Lil' Tasty morphing into a full-blown channel. But seriously, what is Luber? This is all an elaborate joke right? If it's not and Lil' Tasty is really a real person, then I hope there are a lot more videos of this girl soon. Too funny.
