-Scan the room for eye contact
-If any girl shoots you any EC, go up to her and start talking to her while giving her deep EC
-Speak in a soft, deep voice
-Only say just enough to keep the conversation flowing, but nothing more
-If there are any awkward blips yet she's still being friendly, just HOLD the EC - this is what we call sexual tension.
-TOUCH her ASAP (start from friendly shoulder touches to more sexualized things)
-Handshake with your palm up and hold that *****'s hand if she's giving you good non-verbals
-You are a man with a **** and your non-verbals better look like it.
If you do the above, you will not even need to verbalize your interest, she will know exactly what is up from the moment you look at her. Seduction occurs on a non-verbal channel, which means that, so long as you're not autistic/socially retarded, what you say DOESN'T FVCKING MATTER.
And for god's sake, do NOT use PU theory routines or lines. It is impossible to talk your way into a girl's pants. If she likes what she sees, she's going to test whether or not you're socially retarded (i.e. can you keep a conversation going?) and whether or not you can be up front about your attraction (this is largely done through non-verbals in my case [eye contact, the prosody of your speech, physical proximity, etc]).
If you don't believe me when I say that what you say doesn't matter, look at the supposed PU guru's girlfriends. They're busted. Supposedly, these guys can talk really well and they're all great flirters, but guess what ends up being the deciding factor? That's right, something you can't really change without hard work: your looks and your non-verbals.
