Smile Dip is a fictional hallucinogenic candy introduced in Gravity Falls, the Disney animated series that premiered in 2012. In the episode, Mabel Pines eats the banned sweets at the Mystery Shack and experiences vivid, colourful hallucinations while giggling uncontrollably. The moment became a lasting fandom favourite and is regularly clipped for reaction edits, because Mabel's blend of innocence and total chaos sums up the show's humour and remains widely shared years after the series ended.
