How it's used
This is a harsh, vulgar insult used to attack someone's intelligence or decision-making. It functions as a predicate adjective and is almost exclusively used when someone is extremely frustrated with another person's incompetence. Because it is quite offensive, it should be avoided in professional or polite social settings.
Examples
Do you have shit for brains? Doing such stupid things.

Common mistake
Do not use this to describe someone who is simply forgetful or having a bad day. It implies a fundamental lack of common sense or stupidity, so using it lightly can easily start a serious argument.
