How it's used
Used exclusively as a harsh insult to imply someone is incredibly foolish or incompetent. It functions as a predicate adjective phrase, often paired with a rhetorical question to emphasize the speaker's frustration. Because it is vulgar, it should be avoided in any formal or professional setting.
Examples
Did you have shit for brains? You are so stupid at work.
He always does stupid things, he really has shit for brains.

Common mistake
Do not use this phrase literally to describe someone's diet, as it is strictly an idiomatic insult. Using it against someone you do not know well will likely lead to a serious confrontation.
