Definition
To have shit for brains; to be extremely stupid.

How it's used
This expression is a harsh, insulting way to label someone as profoundly unintelligent or irrational. It functions as a predicate adjective or a descriptive phrase rather than a literal description of anatomy. Because it is highly offensive and vulgar, it should be reserved for intense arguments or when venting extreme frustration about someone's incompetence.
Examples
He always does such stupid things, he really has shit for brains.

Common mistake
Do not use this in professional or formal settings, as it is considered a strong insult. It is not a playful way to call someone silly; it is a direct attack on their cognitive ability.
