Industrial Grade Poop

A large poop where total disregard for courtesy flushing and toilet clogging potential is taken because of the industrial grade toilet you are pooping into (the ones with the really powerful flushes that can likely flush down an entire cow). Normal 3 flush poops can be taken in one sitting by the industrial grade toilet.

Man, I just dropped an industrial grade poop. Couldn't even see the water in the toilet bowl after I was done, but the flush was no problemo.

There are various infection routes such as air infection and contact infection.
Treatment has not been established yet.

weapons grade autism

A type of stupidity so advanced it could, in the right hands, topple nations.

What kind of weapons grade autism did they hit you with that made it seem like a smart idea to play slap tickle with a grizzly bear?

5th grade

The grade that is usually the last year of elementary. The 5th graders love being the oldest in the school and the 1st graders think they are soo tall and scary. Once you see the middle and high schoolers you’ll realize how small you are.

Those 5th graders are in their last grade of elementary school!
