When you try to pull an upper decker and miss then hit the seat causing a mud saddle
" I wanted to leave an upper decker for the guy who mud saddled me, but I missed and left a fresh mus saddle"

When one person craps with such volume and force that it bounces back and ends up on the bottom and top of toilet seat leaving a saddle of shit for the next lucky person.
" Dude I have to crap so bad but Jim Dye just left a mud saddle for me in the bathroom! That guy can really blow some brutal mudd"
