What does it mean if a guy puts his hat on you?

Well, based on some serious investigation and research it could mean any of the following: 1) He's embarassed to be seen with you, and is hiding you from something. 2) He's sick of carrying his hat or it's not "hat weather". 3) Your hair is looking rather unacceptable today and he's helping to maintain your integrity. 4) He's really into you... and it's a way of showing his affection - especially if he's shy. Or a mixture of all/any of the above. it means that a guy put his hat on you and that you are obessed with him!
