Place it at the peak of an entrance or reveal, then follow it with Bruh for a deadpan reaction or Emotional Damage when the joke turns into a roast, keeping the horn as the opening punch.

This is a very short train horn blast, lasting under a second, used as a Filipino meme sound. The single loud horn hits suddenly and cuts off quickly, giving it a brash, attention-grabbing punch. It feels funny and startling rather than serious, like a comic interruption dropped into a joke, a reaction or a playful edit when something needs an exaggerated arrival.
