A literary or spoken phrase that combines elements of "WTF" and "cool story bro". Laced with condescension "derp" is a common form of web-based libel that is almost didactic; however not quite as it is generally a sardonic gesticulation rather than moralistic chastisement. The spoken sense of the world itself conveys an intrinsic feeling of disappointment with a subtle hint of disgust and an overtone of rebuke.
