From my experience you dont even have to say one word to them if you have proximity IOIs (they are farkin brilliant) lets take this as A1.
I see the proximity when im dancin with my mates, not eyeing the dancefloor like a predator. Im just throwing some shapes.
I look at them like ive just noticed them, smile, take their hand and give them a spin (compliance - A2) girls find it really funny when you spin them. If they like it, pull them in for a close dance, nice and confident, fun and sexy! I mean u should be pressed lightly against her, it works better if she faces away from you arse to ur front so its not too intense.
Then... after youve dance for 10-20 seconds, push her off! Go back to dancing with your friends, if she doesnt come back then youre done for now, well done. 9 times out of 10 in a minute or 2, boom proximity IOI again, ignore if you can.
After a while give them some more attention, pull them back in for a grind, now were getting a bit sexier, i like to smell their hair and maybe press a bit closer. If they like this, turn them round lightly pull thier hair from their face and BOOM! Pull that trigger baby a nice fun kiss!
Dont kiss for too long, dont kiss too much on the dancefloor if its going well lead her off then you can start TALKING not farking, put it away boy!
If at any stage it seems uncomfortable, just BAIL my friend, dont be the guy that doesnt get the picture, go back to your friends and dont even think about what just happened it doesnt even matter! The main problem is cockblocks and tbh just let them win its better for you unless you have good wings. You dont get emotional and needy like those stupid AFC cockblockers go and dance with ur friends!
