Oort Cloud Fallacy

"The Oort Cloud Fallacy occurs when someone argues that something must exist or be true simply because it is theoretically possible or hasn't been definitively disproven—especially when the claim is distant, vague, or unverifiable. The fallacy draws its name from the Oort Cloud: a hypothetical region of icy bodies surrounding the solar system that has never been directly observed but is widely accepted due to indirect evidence."
"Hey John, do you believe God exists." "We have no proof he doesn't so he must." "Oort Cloud Fallacy."

Letterman's Fallacy

The letterman's fallacy is a scenario in which you are asked a basic question and extrapolate your answer in order to gain a better understanding of the question and this in turn is then used against you to gaslight you into a malformed position that you do not necessarily stand for.

The name letterman comes from the fact that it sounds fancy to say.
Person 1: "If you were a goat would you fuck a goat?"
Person 2: "Would I have the brain of a goat or a human?"
Person 1: "Ah so your a goat-fucker"
Person 2: "So you're going to gaslight and letterman's fallacy me wowza"

Toyu Fallacy

An opponent predicts exactly what you would say, but refuses to, or can't explain why you are wrong. This is an anti argument because the opponent isn't making a point nor debunking yours.
Joseph Joestar knew DIO would say "kono dio da", however, that does not change the fact that DIO can rock his shit.

During a debate about the wage gap, a leftist says to a right wingerin retaliation to an argument they made: haha why did I somehow know that you would say that "the study only compares two checks between a man and a woman. It does not not take the other factors into account, such as hours worked, efficiency of the product, etc". That means that you're wrong because I knew you would say that. They used the Toyu Fallacy

Sam Fallacy

The uncontrollable urge to assume that wanting to sleep with your friends' moms is just something everyone does. It's less about logic and more about projecting your own instincts onto the world.

Logical fallacies

A useful set of 'refutational tools' whose usage is mainly seen in random internet arguments but can also equally be applied in the IRL realm too, such as against your wife or your boss. The former scenario is where people often abuse logical fallacies to the point of committing a fallacy fallacy, so be wise and use them sparingly and only as a supplement to your argument.

Also related to non sequitur.
1) Jim called out his boss by using logical fallacies to poke holes in his ridiculous decisions.
2) Tommy used logical fallacies to his advantage in order to expose the inconsistencies in his girlfriend's reasoning with regards to how he should spend his money.
