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?
When you absolutely fucking yam the individual ingredients of an egg McMuffin into your girls pussy, proceed to vehemently rock her shit to assemble the sandwich, add your "special sauce," and have her eat it.
"Hey man, why you be stoppin by the grocery store so often?"
"Oh Jessica got really into McMuff'n lately"
Friend 1: What did you and your girl do last night?
Friend 2: We went out to eat..
Friend 1: What did you have?
Friend 2: An egg mcmuff
Friend 1: Oh snap. Thats wassup.
