Jake the Dog is one of the main characters in Adventure Time, the Cartoon Network series created by Pendleton Ward that ran from 2010 to 2018. Voiced by John DiMaggio, Jake is Finn's shape shifting companion, known for his relaxed attitude, silly confidence and sudden loud outbursts. Short clips of his lines later spread across soundboards and meme edits, where fans isolate the funniest deliveries for reactions. This Big Liver line became useful out of context because the phrase sounds absurd while the delivery feels triumphant and celebratory.
