The pissed off is a result of giant piss eaters getting sick and tired of the Piss off and are no longer as easy going as their ancestor, in fact they are the complete opposite. 70km of pure rage they have specialized half of their eye thingys into angry eyebrows to make them look madder and are completely red because they are angry. They have grown 2 of their legs and claws to become powerful piss off destroying devices and specilise as a very violent cleaning service for giant piss eaters. They have become predatores that only eat piss off. The fact that thier name “pissed off” is very close to the name of thier enemy “piss off” only fuels more rage.
