look up any word, like columbusing:
A term used widely by South Africans to exclaim dismay at another road user or offensive person also threatening with violence to follow. Originated from the action of slamming your hands on a car’s hood (bonnet) to get the attention of the driver.
If you continue moving forward and hit my bike, I'll tap your bonnet.
