The act of performing cunnilingus while eating a savory McDonald's Egg Mcmuffin. The greasy slurry of half chewed egg, ham, and English muffin acts as a natural lubricant and flavor enhancer. A must for any lesbian fast food enthusiast.
I'm so glad I made it on time for McDonald's breakfast. What's a Sunday morning with the the Wall Street Journal and a little Mcmuff diving?
