When a man proceeds to squat the scrotal region over his partner's forehead, begin to masturbate so that the scrotum proceeds to bounce on her forehead. This creates nut butter, thus the buttermaker. For best results, run for 5 miles to create a sweaty scrotal region. The additional salt in the butter is for her pleasure.
