Buzina XpqX circulates online as a short user-generated meme sound, credited in its file details to Dilera XpericaqX, with no widely documented film, television or game source behind it. Its name uses the Portuguese word for a car horn, which fits its loud, attention-grabbing character and its use in short-form edits. The clip has stayed in circulation because it is instantly recognisable, easy to drop over an entrance or a punchline, and works without any dialogue or explanation.
