Did you know that Pimp My Ride first aired in 2004. That is 18 years ago. A whole generation of now growns ups don't know the show.
I'm old enough to remember the show Pimp My Ride, but I don't recall Xzibit ever having that "catchphrase" on it.
It wasn't an exact catchphrase, but a common theme of the series was that they would figure out some non-car-related thing that the person liked, and work that into the car. Then Xzibit presenting the car to the person would be like, yo, we heard that you like fish, so we installed this 20 gallon fishtank in your trunk. Thus spawned the meme.
Like the Bear Grylls thing, it's not like he drinks his own urine in every episode, yet it was enough to spawn a meme.
Maybe someone liked cars and he put a car inside their car!
I've seen reruns of that some three years ago. The new generation knows about the show, and shitty cars being made more shitty is timeless.
I miss that show. It was so over the top and encapsulated it's own era so well.
It's a meme now, don't worry, they know - I never watched the show myself
