This old fart had to look whip up in the urban dictionary.
When the steering wheel was first put into use in automobiles, it was called the "whip". The whip is what you used to control the horses on a stagecoach, hence the analogy. Many years later, various hip hop artists noticed that the Mercedes-Benz logo resembled a steering wheel. They then proceeded to use the old term "whip" to describe any Mercedes-Benz vehicle. The term has now been generalized to classify any expensive automobile.
A fast, expensive car, such as an Aston Martin. Sometimes used to describe vehicles of a lesser extent in areas of lower standards. (i.e., ghettos)
A whip has simply come to represent a car. It has been said that it was used a long time ago when a whip would be used to steer the horse-drawn carriages. It is used in hip-hop fashion, and it has come represent any car not neccesarily a really nice car.
Could be a FUN car. So, here's my whip ...
It's a smart. In forty years of driving, the most fun car I've owned.
I've had quite a lot of cars over the past forty years, including a 1966 Olds Toronado which was a lot of fun more than
three decades ago.
But, I only paid $2,500 for it in 1976 (ten years old) ... the CV joints needed replacing at a cost of $1600, that killed it for me. What a boat that was. But, it had a lot of features that were really innovative for its year of manufacture, and I appreciated that. Almost as cool as a smart (when gasoline was 35¢ a gallon).
smart's parent company is Daimler, who also owns Mercedes-Benz.
