A meme originating from Panic! At The Disco's week 5 tour recap video, in which Brendon Urie throws a tantrum and someone in the background shouts "Dan, get the granola" requesting the band's drummer Dan Pawlovich to get said granola.
Whilst derived from the video the creation of it as a meme is credited to Instagram user folieakenny.
