My experience must differ from yours, but metrosexual and hippie are useful superficial descriptors for many people I encounter. I know many people who would self-identify as either. When I was completing college I also knew several people who would gladly self-identify as brogrammers. The terms do not describe freak phenomena that we can sweep under the carpet.

To me, brogrammer mostly can be reduced to spending too much attention on vanity and not enough on the well-being of others. There are many synonymous terms, but this one is valuable for its succinctness.
