There is exactly zero things this entails I care to know anything about. I never was part of or even interested in any kind of club scene. I've always considered myself too intelligent for bitchy prissy girls. Selfies started with the younger generation and, as far as I observe, the only good thing about it is it makes it easier to know which friends to avoid traveling with.
The most absolutely horrid thing about this song, rather than mocking it, it was created to celebrate the ego worshiping practice of the selfie. Really, by the end of the song, with all the horrible selfie pictures of horrible people (including a glasshole doing duckface), the generic electronica club music, the voices of those two high maintenance cum receptacles and hashtags peppered throughout, well, everything, it makes me hate technology. I'm now an IT who hates technology. I'm screwed!
Once again, thank you hipster douchebags for taking something wonderful and completely f--king it up for the rest of us. I hope your daddy's money runs out very soon.
