Appeal to ridicule
From Wikipedia, the free encyclopedia.

The logical fallacy of appeal to ridicule presents the opponent's argument in a way that appears ridiculous and mocking it.

Examples:

1. If Einstein is right that would mean that when I drive my car it gets shorter and heavier. That's daft!
2. You can't have a cat called Fido. Calling a cat Fido would just be silly!

This should be contrasted with reductio ad absurdum which is a valid logical argument form.
