Definition

The vehicular equivalent of a jump scare, where a driver sneaks up on an unsuspecting pedestrian and unleashes their horn at maximum volume for pure comedic effect. It's equal parts prank and public menace, guaranteed to spike someone's heart rate and possibly ruin their day. Essentially, it's assault by automobile horn, but make it funny.

Example Usage

My brother gave me a honk-by while I was walking to the mailbox and I nearly jumped out of my skin.
