Lumpy Space Princess debuted in Adventure Time, the Cartoon Network series that premiered in 2010, where she was voiced by creator Pendleton Ward. A floating, purple, cloud-like princess from Lumpy Space, she became a breakout character for her valley-girl delivery, catchphrases like oh my glob, and for using lumping in place of stronger swearing. Clips of her outbursts circulated as GIFs, edits and soundboard buttons during the show's run, and her bratty yell remains a shorthand for spoiled, theatrical outrage online.
