I'll probably catch some flak for this, but it's possible that the short hair is signalling "I'm at the bar for the ladies".

Yes, it's an unfair stereotype that a woman with very short hair is a lesbian. However, in our culture long hair signals femininity and short hair masculinity. Wearing it so short is a flaunting of traditional cultural signals, so it's just possible that on a subliminal level it's a turn off for men.

And I got a vibe from the video that the friend might actually be interested in this woman but wishes she looked more feminine.
