No idea what you meant by that sorry. And now there's that other meaning..something about metrosexuals with beards or something. But either way, not clear to me at all what you could mean.
Hipsters care a lot about signaling that they prefer fringe/niche/"non-mainstream" culture. Since it is all about social signaling rather than actually enjoying a wide variety of culture, it is just as important for them to signal what culture they don't associate with, and that is decided not by the quality of the music/film/food itself, but rather based on whether other people why enjoy it are "down with it" or "mainstream".
Radiohead is a pretty popular and well-known band, so you have to pretend you don't know them, while at the same time disparaging them - not for anything related to their actual music, but for the people liking them not being hipsterish enough. This is the epitome of hipsterness.
