Someone who generates ideas (about anything) as tirelessly as a hamster generates squeaks from the hamster wheel. NB, speaks to quantity moreso than quality.
"Paul is a crazy idea hamster; he gave me at least 4 plot bunnies."
An Idea Hamster is often an intelligent person who sometimes cannot communicate when concentrating in a very busy environment, but is still full of ideas.
An Idea Hamster, often someone who’s neurodivergent, always seems to have his/her/their idea generators often running from after breakfast until bedtime.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
