As a general rule, don’t just walk up to a woman and start dancing with her. Whether it’s more of a casual, barely moving to the beat kind of dance or something a little closer, just don’t do it unsolicited. You especially don’t want to walk up and just start grinding on her. Nothing spells out awkward, weird old guy more than that, and you don’t want that stigma. Her invitation to dance won’t be an engraved one, but it’ll be a subtle glance, or a crook of her finger, and then you can go and dance close to her. Fitting in seamlessly against her to dance will make you seem smooth as opposed to desperate.
This is another one you need to be careful with. Sure, you can have the bartender send over a drink for the lady, but make sure when she looks around to see who sent it that you aren’t leering at her. That’s just… weird, and it’ll be a huge turn-off to her. The key to buying a drink and coming off as charismatic rather than creepy is all in how you act after she gets it. Don’t say something like, “You looked like you needed more booze.” That gets heard by a woman as, “You didn’t look willing enough yet, so I figured I’d get more alcohol in you.” Instead, slide onto the stool next to her and tell her that she looked thirsty. There’s a double meaning to that phrase that she may just pick up on, but don’t push it.
Again, no unsolicited sexual propositions should be made. Those are about as lame as unsolicited dick pictures sent to her phone. Nothing makes a guy look tackier than asking a woman for sex out of nowhere, so don’t do it. You can’t just walk up to her and ask if she wants to go home with you, because there’s certain finesse to it. She needs to be receptive to your lines, and she should be flirting back with you. Only then should you bring up the idea of taking her home, and never in a campy, cheesy way like some idiotic college frat guy’s pickup line.
