Stupid & Thick mean the same = not intelligent Thick is more colloquial or slangy. "Daft" has a different connotation. It's usually not meant in an insulting way, and is often used when somebody has done or said something that doesn't make sense or is silly. Example: John: " i was looking for my reading glasses everywhere, and then i realised they were on my head!! Alice: " Oh, you are daft!! " [ but she loves him all the same haha ] :-)

Similar meaning. Slightly different usage: "Daft" and "thick" are colloquial. "Thick" might be more hurtful as it is generally used to describe someone's general character - whereas "daft" might be used to describe a single action or opinion etc. You sometimes need to be very careful about using these words - they could be hurtful.
