Play fighting is not cheesy. If you're just poking each other in the stomach, play slapping, tickling, whatever... and then you gently tackle and kiss, most girls I know would find that spontaneous and romantic.
Massage is too played, it used to be a good idea.
As long as she's not piss drunk I don't see it as taking advantage here. Buzzing just makes things less awkward, which is simply going to make your move more likely to be accepted... not because she's wasted, but because everything is less weird.
If you both smoke, go for it while blazing. Not only will it be amazing once it works, but people get outrageously horny on weed, and yet there's not the "Oh shit, why did I do that?" feeling you get with alcohol. You know exactly what you're doing, the hormones are just a little more active hehe.
The best way to do it really is after you've both been laughing, preferably if you made the joke, and when your eyes kind of meet and there's clearly nothing to say, just lean in. The official distance as decided by Ladies Men is to go in 90% and let her cover the remaining 10%.
Hope that helps.
