Translates roughly to playful nonsense statements referencing SpongeBob SquarePants (I'm SpongeBob) and Patrick Star (I'm Patrick), from the popular animated show. 'Doubi' can mean someone silly or goofy, so it also emphasizes having fun and being playful with humor inspired by the two cartoon characters.
