Most frequently used when playing the card game Bull Sh*t (bs- other wise said bad spaghetti). After the person next to you has laid their card/s down, you say peanut butter to indicate that you lied and got away with it.
Bob: (lays down cards) 3 sixes.
Dan: (lays down card) 1 seven.
Bob: Peanut butter!

Used to be my favourite snack until the I learned the FDA allows up to 30 or more insect fragments, or one or more rodent hairs per 100 grams.
Buddy P- "Hey, What'd you have for breakfast"

Me- "Why, my favourite snack of course, Peanut butter on apples"

Buddy P casually replies- "oh so you mean you had rodent hair, cockroach legs and peanut butter on your apples?"

Me- Fuck you enemy P
