i remember a few years back when i was livin' up the single life... i ran into a situation like this.
i took this girl to a bar/grill that i liked... great food. anyways, the girl was really hot - to the point where anywhere she goes, guys hit on her. so we sit at the bar and are having drinks and eatin and havin fun.. and i excuse myself to go to the bathroom. i had noticed there was a group of 3-4 guys sitting at a table behind us... now keep in mind, im only in the bathroom for a couple minutes. yet as im walking back to my hot chick, these jerkoffs moved from their table to where i was. i kid you not, one was literally sitting in my seat next to her, with his chump friends sitting next to them.
without hesitation, i walked right up behind the dumbass in my seat, very firmly put my hand on his shoulder and neck and said, "Youre in my seat." and stared at him, HOPING he would make something of it. him and his friends said sorry and left. after i sat back down in my seat, she gave me a big kiss and we both laughed about it.
so you gotta ask yourself, whats the guy doing to you?
do you know him personally or are these guys strangers?
if you see a girl you wanna get to know more, go for it. if shes with her boyfriend, obviously its a bad idea. if shes with a guy shes fvcking, not a great idea either.
if shes just with friends, then you need to be respectful of her company.. to a certain degree. you dont owe them anything, but be courteous. introduce yourself and do what you gotta do to get to know your girl.
now, if youre getting to know a cute girl and some random douche butts in and tries to **** block...
first off, you definitely dont owe him anything. be the bigger man dont stoop down in level if he resorts to childplay. let him come off as stupid. take it on a case by case basis, but honestly just be the better man.
secondly, watch how the girl reacts to this. if she gets excited about the idea that you and this other guy might start fighting over her, or tries to egg it on... NEXT. not worth it.
what you shoot for in a situation like this, is that the girl is so into you that when the random tool tries to butt in, she is just as annoyed at him as you are. that when he gets the hint and walks away, you both look at eachother and say, "man.. what an idiot!"
