Mchashy 

To make the Mchashy, you go to McDonalds during breakfast hours. You order 2 hash browns and either a bacon, egg, and cheese biscuit or a sausage, egg, and cheese biscuit. You then put the guts from your biscuit of choice in between the two hash browns and BAM you have a Mchashy. It is guaranteed to taste better than sex and raise your bad cholesterol 25 points.

Dumbass: McDonald's breakfast sucks
Me: Have you tried the Mchashy
Dumbass: What the hell is that
Me: Read the definition dumbass

Creamy McNash 

Can be likened to a Dirty Sanchez, except the man's semen is used in place of excretion.

Some people like to Dirty Sanchez. Personally, I prefer a Creamy McNash any day of the week.
