Dead hipster garage sales are amazing

I can't really tell if this is supposed to be ironic or not. I guess I'm not hipster enough to get it.

I'm glad to see hipsters inexplicably have night vision goggles. I suppose that might be so they can see other hipsters approaching in the dark to make sure they look ironic when the approaching hipsters get nearby so they make a flippant acknowledgement of the approaching hipsters' vintage T-shirt or nut-strangling jeans.
