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.

Niagara Grumper 

An explosive shit. Comes pouring out of your ass with seemingly no end to the flow. Like a hot waterfall of shit.

I ate some bad oysters last night and today I experienced the worst Niagara Grumper. I couldn’t get off the shitter.

Forrest Gump when Forrest Gump's mother had sex with a superintendent of school district to grant Forrest Gump access into public school and not a special school for less fortunate.

In the PTA meeting held at the town hall a mob of parents held signs in protest and loud speaker saying "Mrs. Gump had sex with the right person to get her slow handicapped son into our public schools which created a distraction to all other children's learning." when interviewing another angry parent, the parent very frustrated in demeanor said, "She can't just gump the super-intendant for her boy to be placed into schools made for regular kids. She's done this before with parking tickets getting thrown out, to returning opened electronics that she obviously used and damaged. she gets away with everything by her gumper ways and now it seems she is gumping her way into our public school.
