So, you need to isolate a girl from a group? Going out for a cigarette is a great way to do this. However, running tight cigarette game matters. No girl will be impressed with that guy with an old pack of Camels and a shitty lighter that doesn't work, so having good logistics when it comes to your isolation move is a must.

Lighter: Don't be the guy with the 7 for £1 lighter that doesn't work in the wind. If money is tight, grab a £1 Clipper, if you have more to play with, invest in a good quality lighter that will be an effective DHV, such as a nicer Zippo or one of the many premium lighters on the market. Nothing is more beta than a guy who can't light a girls cigarette.

Case: A crumpled old pack never looks good, especially if you are from the UK so got them cheap duty free in France for example. Spend the £10/20 on a decent cigarette case, for some reason I find girls are really impressed by engraved ones. If you are in a financial tight spot the case can hide low end cigarette brands, but that's still not ideal.

The Cigarettes themselves: obviously, don't be a cheapskate and turn up with the bottom of the line shitfests from ASDA or Walmart. Also dont buy anything 'slim' if you want to attract girls of the feminine gender. Malboro and other good brands are fine, but I find what you really want are Sobraine Blacks, the black and gold film design seems to make them look far more expensive than they really are, and they can be a DHV in my opinion. In addition no other guy will have them, so you'll be remembered for it, which is helpful.

The Obvious: don't give a girl Cigars, they will be sick, and it's a waste of perfectly good cigars. Don't buy a cigarette holder, that's just gay. Don't give out rollies, unless it's weed, as people will assume it is, and moreover, they tend to fall apart, and make you seem a cheapskate.

P.S

TRP Redditor JamesSkepp also suggests trying the following:

"im going for a smoke, come with me", grab her hand and lead.

You'll either get compliance or not. If she want's to be isolated, she will go, if she doesn't, she's not that attracted and isolation won't allow for more escalation in this case.

Attraction = compliance.
