Commonly seen as an immediate red-flag to someone who has no idea what they are talking about, and an early sign that what they are about to say has absolutely zero evidence to back it up.

It's a Fact Card

The tactic of ending debate by loudly declaring one's own position as an indisputable "fact," thereby framing any further disagreement as irrational denialism. This move aggressively shuts down nuance by claiming the mantle of objective truth, often by cherry-picking a single statistic or a broadly accepted premise while ignoring context, interpretation, or counter-evidence. It's a power play to position oneself as the voice of reality and the opponent as a "fact-denier."
It's a Fact Card *Example: In a climate change discussion: "CO2 levels are rising. That's a fact card. If you disagree, you're anti-science." This ignores the nuanced debate about impacts, mitigation strategies, and economic trade-offs, reducing everything to a single, weaponized data point to foreclose all further conversation.*

Pee Calculus

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.
