The meme comes from the movie Breakin' 2: Electric Boogaloo. The film's title features a rather cheesy rhyme scheme. It released to terrible critical reception. Citizens of the internet eventually started utilizing this secondary title to mockingly suggest sequels to their favorite media. The humor is especially effective when the media in question is considered "serious" or "dramatic", since a goofy sequel would be absurd.
An example from the show would be an episode with guest RoboRob, in which Lars asked if the latter would participate in the soundtrack composition for a hypothetical "Inception 2: Electric Boogaloo".
