Breakfast mess 

A breakfast mess is a midwest diner breakfast staple, consisting of several ingredients like pre-cooked (usually leftover baked) potatoes, that are either diced or shredded, some type of breakfast meat like sausage, bacon, or ham that has also been diced up. Then some diced onions, bell peppers, can mushrooms, and eggs (scrambled into it, or over easy). All cooked together, then topped with sliced American cheese or shredded cheese.

I went to the local diner this morning and the cook made me a breakfast mess.

Messy Breakfast 

Similiar to the Messy Dinner and Messy Lunch. This however, lacks the two primary components of the dinner/lunch. Instead of smearing shit and/or peeing, you smear smegma on the person's face. IE: Dick Cheese

Those two homos just gave each other a messy breakfast. See Messy Dinner, Messy Lunch, Messy Brunch.
