The group will more or less compliant to her
The better way to do it is to win the influence of her and her friends. It’s also a more sustainable manner.
I know, some times the friends of girls can be a major cock block. I’ve been there multiple times. The best strategy is to often kill them with kindness. Talk to the fat friend. Imagine how she feels when her friend always gets all the attention when they go out to the club and she gets completely ignored.
If two people lead a codependent relationship, there’s not much you can do to convince them otherwise
Some times, things may not go your way. She may be overly invested in her friend’s opinion of her rather than actually having fun in the club and meeting people. They’re not right for you, you simply have to move on.
The first rule of social skillsets is this: make it fun! Come from a point of adding value to someone’s night. Don’t be a social leech. Bring fun and add something to the group.
If you’re dressed well, and are having a good time and experience good emotions, you’ll automatically feel good and be able to ‘add’ to the fun of someone else’s night.
Talk to her guy friends and acknowledge them. If you notice something cool about someone, be it a guy or not, then say it. It’ll show that you have social intelligence. Furthermore, everyone likes to be appreciated and talked to
Most of the times, the most beautiful girl will have the highest social value in the group. Sometimes, you won’t actually have to win her friends over, as they are all following her lead in the interaction.
However, that’s not always the case. It’s your job to lead in conversation, physicality, and logistically. How good you do this will determine if the rest of the group would comply or tell you to fuck off.
You’ll have to aware of the self-interest of everyone at given point of time. What are their intentions and behavior? What do they want? Do they like the same girl as you do, and if so, how are you going to manoeuvre yourself in a socially savvy manner to get the girl that you want.
