When a Southern lady says "Bless his heart" regarding someone, it means that he is as stupid as a box of rocks.

A phrase uttered as an expression of sympathy, probably originated from southern US states. Usually tacked onto the end of a sentence to "soften" the blow as this is often used to describe something unfortunate. Can also function as bless her heart for women.
