So there was this advert where some hipster levis type girl was running around the streets and then through a building and it was all very edgy and predictable but I don't remember what it was advertising - possibly trainers or jeans or maybe something else - anyway there was this modern sounding punk/ska track in the background, all skanky and quite upbeat with a trumpet line and the lyrics were like:

aaaaaah derpy derpy derpy derpy derpy derp
derpy derpy derpy derpy derpy derp
derpy derpy derp and they never understand
keep on pushing keep on pushing keep on pushing derp
derpy derpy derpy derpy derpy derpy derp

Obviously it didn't say derp or derpy but I can't remember the words. At the end the hipster girl emerged on the roof of a building.

So tell me DiS - what the hell was that song?
