Mario Kart

Alright, listen up, buttercup. This "joke" is basically saying Peter Griffin was having sex with the listener's mom, and he's comparing her to the Mario Kart game because she was easy to ride. Now, you probably don't know what sex is, but trust me, it involves two people and some questionable decisions. Plus, you're probably too young to know about Mario Kart too. Go back to playing with your blocks.
