M&M's is a type of candy.
When Bart was suggesting ideas for a food gift for Juliet Hobbes, he thought of M&M's. However, Lisa refused it, because if she picked plain, she'd look cheap, but if he picked peanut, Juliet could have an allergy and die.
In Treehouse of Horror XXIV, when Bart asks if they could have candy, Marge offers the kids only one M&M each.
