The homeland of all decepticons, as stated by John Green of the Vlogbrothers. It is safe to assume that worldsuck emanates from the land that is Decepticonia. Decepticonia is the anti Nerdfighteria.
Decepticon: I think I'll go out on the town and spread WORLDSUCK like peanut butter on bread!
Nerdfighter: Whoa, whoa there, mister! This town does not need any more suck! Go back to Decepticonia!
Decepticon: Yeah, well...YOUR MOM.
