This is about the perk. If you are looking for the actual Biggest Asshole on the Planet, see Maccy Man.
Biggest Asshole on the Planet is a perk in Fallout: Eleventy.
Congratulations! You just doomed the planet to bad grammar and stupidity. You truly are the Biggest Asshole on the Planet!
Receiving the Perk Edit
The Perk can be received by using the Special Disk in the quest, Double Trouble. It is a reward for using the disk instead of destroying it and unleashing the Troll Army.
The perk raises ST, EN, AG, and LK to 10 , and lowers PE, CH, and IN to 1.
