An exclamation used to express great appreciation for pointless yet amusing curiosities. Such curiosities may arise naturally or be man-made, in which case an inordinate amount of effort put into creating something so pointless and bizarre heightens the propensity for it to be described as angbadang.
Also commonly used as a superior and less dickish form of YOLO.

The term was first coined by John "TotalBiscuit" Bain during recording of the twenty-fourth episode of the TGS Podcast, on 12th September 2012.
