The biggest risk is her bf being around so make sure she is not with a male. Cold approaching is scary but there is a thin line between fear and fun.
This is pure keyboard jockeying. I've approached 100s (probs 1000s?) of mixed sets--including couples on dates. When I was starting out, my motto was:
Any girl, any situation (I've gotten a lot lazier the past few years unfortunately). I've never had a guy swing on me once--and I've been in cities where there's plenty of violence. Usually he'll just 1.) Grab her or 2.) Say that's my gf. You just apologize, empathize, befriend. Easy.
I've had guys step to me exactly twice. One was years ago in a college bar where this guy started talking **** so I started macking on the girl he was with to prove a point (didn't even like her--it was just my ego at the time and I kinda provoked him). Last night I approached a girl who was in a group with like 7 other guys and 1 other girl. She opened and hooked. Turned out one of the guys was her bf and got heated and stepped to me. I just raised my hand, said, "Look, man. I had no idea. Props dude. Take it as a compliment." Calmed him down a little and then dapped him up (when you reach out your hand, people's instincts are to grab it, pulled him in for a shoulder hug). His friends ended up apologizing to me on his behalf and I befriended one of them.
@AttackFormation We've both been here a long time. And we've had 2 very different experiences. Just cold approach. Find RSD Julien's PIMP (it's floating around the internet somewhere) and read YaReally's archives starting with the
Scray FRs. No excuses. Rejection is good for you and I'd rather be rejected a million times than play the victim. Stop looking for IOIs. They're just about meaningless and they're not necessary. If you get blown out off the open, it's an easy fix 1.)
Eye contact--Relaxed, direct, hold it 2.)
Tonality--Loud, breaking rapport (downward inflection). That'll at least get girls to open, even if they're unavailable or not attracted. And accept that at the end of the day, no matter how good you are it's still a number's game (but I'd take my %s and quality from cold approach over OLD any day--I only lasted about a week on Tinder lol).
