Grumper

An especially hot and steamy shit. Grumpers often leave you very sweaty and exhausted. They're mostly taken under less than ideal situations like port-o-johns and bar bathrooms.

Man I was tailgating on Saturday and I had to shit some fierce. I went to the port-o-John and dropped a fiery grumper. My asshole was never the same.
