When a girl finds pleasure in sexual activities including peanut butter. Usually involves nutty or creamy Skippy peanut butter in the genital area. Especially efective when generous amounts are applied to the fist and put places that would not otherwise be possible.
OMG I love doing an amish hayfield to myself every night, the chunky peanut butter kinda scratches my vage and i get off really quick
