A term coined as a play on the popular Maple Dipped Donut from Canadian Coffee and Bake Shop Tim Horton's. It refers to a male receiving oral sex from a female while his genitals have been dipped, smeared or covered in Maple Syrup. Preference is to use real maple syrup over the fake table syrup seen in most grocery stores at rebated prices.
So Mike just told me how this girl gave him a Maple Dipped Blow-Nut once. He can't look at her the same way when he orders a coffee from that store anymore.
