Yo dawg i heard you like 3ds / so we put a ds in the back, in the trunk and in the dash so now you have 3ds
A xzibit-yo-dawg meme.
Xzibit Yo Dawg is rapper Xzibit, host of MTV's Pimp My Ride, a show that put things inside other things in cars. The meme jokes about that habit: "Yo dawg, I heard you like X, so I put an X in your X so you can X while you X." It's the meme for recursion and anything that goes one level too deep.
