Jenna Marbles - What do your nails mean?

Catching up to Jenna Marbles new videos now when I'm back home (with good internet weeh!!)
And I got stuck on this video (being a big nail-maniac and all)
Ofcourse this is not to be taken seriously since it's all jokes and fun but I can't help to recognize myself and others by some of these simple generalizations ~


Warning for "mild" cursing!
