How it's used

This is a highly aggressive and vulgar way to call someone stupid. It implies that the person's brain is located in their buttocks, suggesting that their thoughts are as useless as excrement. Use it only when you are extremely frustrated with someone's incompetence, as it is guaranteed to cause offense.

Examples

He always does things wrong, he really has an ass for a brain.

Common phrases

to have an ass for a brain

Common mistake

Do not use this in professional or formal settings, as it is considered very rude and insulting. It is strictly reserved for heated arguments or when venting to close friends about someone you despise.
