Thread Name: BS: What does 'bonk' mean ?
Subject: RE: BS: What does 'bonk' mean ?
When I used to read about cars and engines at school (ten years before I could drive), "bonk" was used as a term for the sound of a misfiring engine.

from "Secret of the Dragon's Breath: Book Two By Derek Hart"

Usually caused by fuel failing to ignite in the chamber - sometimes followed by a backfire as described in the book exerpt.
