1. A rarely accomplished feat, Mr. Peanut is slang for the sexual act of a man receiving oral sex from female tapdancer with glasses. When the man is ready to ejaculate, he withdraws from her mouth and presses the tip of his penis firmly against the outside of her glasses on one side only. He then proceeds to spooge heavily and completely covers one side of the glasses in a milky white film. To seal the deal, he must then cock one leg over her and take a dump filled with peanuts on her stomach, thus giving her the appearance of Mr. Peanut.
