An expression of condemnation or exasperation uttered by someone (typically a non-hipster) after a hipster has done or said something ill-advised.
"Did you hear that Humphrey got Tulip preggers after he accidentally put on one of the rubber balloons left over from his balloon portrait of Bjork embracing Madonna, instead of a condom?"
(figure of speech) referring to something small that is difficult to find in a large space, it quite literally would be like searching for a needle in a haystack, obviously nigh impossible.
