How it's used

Using this phrase is a very aggressive way to insult someone's intelligence or decision making. It implies that the person's logic is so flawed that it could only have originated from their backside rather than their brain. Because it references a body part, it is considered vulgar and should be avoided in professional or formal settings.

Examples

Are you thinking with your butt? You don't even know something this simple?
He is always thinking with his butt and saying nonsense.

Common phrases

thinking with one's butt (as a rhetorical question)

Common mistake

Do not confuse this with simply calling someone stupid. This phrase specifically attacks the process of thinking or the quality of a specific idea or plan, rather than just describing a person's general character.
