For example, my friend does not really smoke (he does sometimes) but choose to go out and date chics who are smokers. When he notices them wanting to smoke (after eating out) he goes and says he wants to help light it up. It works most of the time, as he's able to isolate with her and escalate.

Are there any fun or grey area escalations especially in public? I particularly get shy or freeze because escalating in public (for me) can backfire and I don't like people looking at me or us. When I get a chance, I always ask if I can peck on the cheek. If they let me, it's usually a surefire way to escalate further.
