Deltarune is a role playing game by Toby Fox, first released in 2018 as a follow up to Undertale. In its first chapter, Lancer is the cheerful son of King, the ruler of the Card Kingdom and one of the main antagonists players face. Short character voice blips like this one were shared by fans on soundboards and in edits, where the extreme brevity became part of the joke. It remains popular with players who use familiar game sounds as instant reactions rather than full quotes or dialogue scenes.
