The act of putting peanut butter on a dog's dick (AKA Red Rocket) and licking it off. Similar to putting peanut butter on your dick and having a dog lick it off, but the other way around.
Dog: (constantly licking lips)
Brenden: WTF, did my dog just lick peanut butter off your dick?
Antonio: Yep, and now I'm going to return the favor with a Peanut Butter Rocket (PBR).
