Bill Cipher appeared in Gravity Falls, the Disney animated series that premiered in 2012 and was created by Alex Hirsch, who also voiced the character. The triangular dream demon became one of the show's most quoted villains, and short clips of his laugh spread through fan edits, meme pages and soundboards long after the series ended in 2016. Because the laugh is so distinct and needs no context, creators still reuse it online to mark a character as chaotic, smug or secretly in control of the situation.
