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.
(adjective) Guano (bat sh!t)+psychotic(crazy); bat sh!t crazy, expressed in a way that is less likely to upset or offend parents, instructors, etc. May even get points for creativity.
Did you see that lady yelling at the W@l-Mart cashier? She was guanopsychotic!
A cannon used in the Subspace Emissary, in Super Smash Bros. Brawl. Controlled by Ganon and Bowser. This was used because they were told by Master Hand (Who was really controlled by Tabuu) to create an army of ships, and a HUGE FUCKING CANNON TO BLOW THE FUCKING SHIT OUT OF EVERYTHING. This would then turn it into Subspace, but suddenly, Kirby destroys the cannon by piercing it with the legendary Kirby Air Ride vehicle, the Dragoon. The cannon then proceeds to FUCKING EXPLODE AND COMBUST ALL OVER THE FUCKING PLACE. Ganon and Bowser then admit defeat and go back to Subspace in the portal.
Luigi: Hey Mario, you see that Ganon Cannon?
Mario: MAMA MIA!
