I think if a guy just randomly massages your shoulders, I think he is interested.
It could mean several things. Depends on where, when, and who he is. It can range from friendly to a "come on".
When your boyfriend massages your shoulders, it means he cares about you.
That means whatever the issue\problem is, its your responsibility. As in Atlas the guy with the world on his shoulders... the problem is on your shoulders.
"My head is on my shoulders" means they are thinking right, they have their head in the right place.
the guy likes you and cares about you or was trying to get your attention
No, a guy on another guy's shoulders does not mean they are gay anymore than if two good buddies are seen together often. Never judge a book by it's cover! Often you will see a winning team hoist the person who made the goal to win a game and they aren't gay.
depends on what the relationship is and how old you are. if you are dating and about ohh... over 18 id say he is trying to get you in a romantic mood. then again that is just an example
'fair shoulders' if used in the context to describe a person, means pale-skinned shoulders
you talk to the guy that is next to the girl who massages your Pokemon
he most likley wants to ask you a very important question.
Either that or he's just having fun in the pool. He probably likes you, but it doesn't necessarily mean that he likes you in any special way at all. Some guys enjoy more physical activity when they play, and given the right circumstances a guy might pick a male buddy up on his shoulders without giving it a thought. Stay friendly with the guy; maybe he is interested. But don't read too much into the guy's ways of playing around.
It means he is showing you how kind & caring he can be.
