In the third video in the OP, she appears to be using a hair clip or band that pulls her hair back. I knew a girl that sometimes wore a pony tail which would pull her hair back kind of like a face lift effect.
This is interesting. She has no make-up at about 0.40 and wears make-up in the rest of the video. This is one of her ghost videos.

I don't know if there's something about Scottish culture where everyone tends to use dirty words now and then. I don't know if they're all like this or not. Where I live the blue collar workers tend to cuss and talk about sex a lot, but in a white collar job you're expected to not do this and act professionally.
