Appeal to ridicule (also called appeal to mockery, ad absurdo, or the horse laugh)[1] is an informal fallacy which presents an opponent's argument as absurd, ridiculous, or humorous, and therefore not worthy of serious consideration.
Appeal to ridicule is often found in the form of comparing a multi-layered circumstance or argument to a laughably commonplace event or to another irrelevant thing based on comedic timing, or wordplay. This is a rhetorical tactic that mocks an opponent's argument or position, attempting to inspire a strong emotional reaction (making it a type of appeal to emotion) in the audience and to highlight any counter-intuitive aspects of that argument, making it appear foolish and contrary to common sense. This is typically done by mocking the argument's representative foundation in an uncharitable and oversimplified way. The person using the tactic is often sarcastic in their argument.[2]
