when someone take a soft crap in their pants so it speads all up and down the crack of their ass, then they sit on another person's face so they can eat the muddy chalupa.
I've decided to propose to my girlfriend, she's so awesome - last night she prepared a muddy chalupa for dinner and I ate it all up!
