Dry-Gulch

When you shit into a toilet and, when flushing, the water rolls the shit around the bowl leaving skid marks all over the inside of the bowl. The appearance looks like you shit into a dry toilet or a "dry gulch".

Brandon:*walks out of bathroom with a smug look on his face*
Brandon's co-worker Jimmy:*walks into stall* Jesus man, what in the fuck did you do in here, there's shit all over the bowl?!? Did you even flush?
Brandon: Mexican buffet last night bro!
Jimmy: You dry-gulched the toilet man - might as well just replace it since we can't use it now.
