Listed as a single long horn honk in the note B and credited to salamisound, the clip takes its page name from the wordplay between honk and Honoka. That pun is why it circulates less as a traffic effect and more as a fandom in-joke, shared on soundboards and dropped into short edits whenever a character introduction or reaction needs a loud, friendly cue. Its appeal is its simplicity: one unchanging pitch, no extra effects, and a duration just long enough to be noticed but short enough to reuse repeatedly.
