it means that he likes you enough to kiss you in front of his two friends, thereby laying a claim onto you.
maybe he's just showing off. he just "like you", but i think a guy is serious about you if he doesn't do that in public... a way of respect. watch closely and observe his next actions
he's telling them hands off xD
well they know yor in a relationship now
Who know's what it means there are to many variables to decide. You were there hope you were watching for body language etc.
He's displaying pride of ownership,which makes u a thing.
It means he wants the world to see/think that he's having sex with you and his friends have bared witness. Seriously if you guys aren't 30+ I highly doubt that your guy is worried about romance/ intimacy rather than look like a lady killer.
it means... that he likes you.
Well, he's proud that you're his, or he's an arrogant jerk that's saying 'look at today's catch' that's just my opinion though :)
it means he is showing off. be cautious and obsurvant of his future actions. he may not be truthful in what he says
Means he does like you.
That he needs more friends if he's only got the two ;-)
he doesn't love you if he didn't post it on facebook to his other 373 "friends"
Staking a claim.
He is staking his claim.
