How could I pick up a girl at a party?

Have a few drinks and make sure you have a good buzz. this will also boost your confidence. so once you feel up to it, go up to a girl or sit next to hear. and just say hey or something. (at this party i realized i had the same phone as some girl and held mine up to hers, and said, "hey were phone buddies" just to break the ice) so we started talking and she seemed pretty receptive (if she seems like a buzzkill or uninteresting move on). i was pretty drunk by now, and everyone decided to walk to tim hortons. i offered her some of my mickey to show im polite lol. (just kidding, to get her more drunk) so while we were walking i just went for it and put my arm on her lower back. she didnt object so i knew i had an "in". by the time we got to tim hortons she grabbed me and jammed her tongue down my throat. we went back to the house party and made out the whole night. i thought i was gunna get some for sure but she had to go home (highschool party) so that was the only downfall. it was fun tho.
