>I'm a little bit autistic >Girl I like and have been

learn to dance, get drunk, dance.
you look cool and fun but you don't actually have to talk to people.

First thing, try to make yourself useful for the party: ask if help is needed with anything: food/music/organisation/transport. This might make you feel more comfortable and entitled to enjoy the party.
You don't have to be the barbecue man or the DJ man that do not enjoy the party.
Then it's all about shutting up most of the time it you are not comfortable with talking.
Make compliments to people you like and find cool.
Don't go too far with alcohol, one or two beers are enough if you want the girl to be yours.
If the girl like you she will try to get close to you anyways so dress and have gums, give her little attentions like getting a drink for her or small things. Do NOT stick to her.
She will be turned off if you show signs of "being too scared to" dance/talk/kiss her. So if you have those intrusive thoughts about looking ridiculous, you've got to answer with "who cares" about what you do if it makes you happy or if you like it. People will just be like "shit he's strange but in a cool way"
Dancing as good as a duckling can be seen as funny and not ridiculous, people can even join you
>>Me at every party dancing like shit filling the dancefloor

I should have been more clear. By a little bit autistic I mean full blown Asperger's. I've never been close to anyone before her. She's basically been my first handhold, cuddle, kiss and conversation longer than 30 minutes.
She knows I have Asperger's and social issues and all of our dates, if you could call them that, have involved just walking and talking and holding hands.

Back to the topic at hand though. I have no fucking clue what happens at parties aside from what Hollywood portrays them as.

from what i can tell theres two things you can fuck up here that you cant recover from.

first of all: alcohol. you are a beta bitch so theres no way you will be able to resist the peer pressure. you will be drinking.
since youre inexperienced DO NOT participate in any drinking games and if you do quit asap.
alcohol works with a 30min time delay. you may feel fine now and then suddenly, bam, it hits you. stick to beer if possible even if you dislike it. 4 or 5 beers all night for a noob would be ok. if you do go for harder liquor stick to 3 drinks all night at most. protip: monitor how drunk you are on the shitter, its the neutral benchmark.
more than that will net you all the effects youre afraid of: nausea, loss of control, telling your oneitis about your worldview.
drink slowly, be smart about it.

secondly get amoungst it. maybe youre a complete autist. its still better to sit in the group and talk nothing but spaghetti (at least that way youll be the weird guy, people recognize your existence) than to sit at the wall and say nothing at all.

stick to the girl you know, dont be scared. have fun. the other people there arent the bullies you expect them to be.

>I have no fucking clue what happens at parties
you go there, talk to people and play increasingly retarded games as the night progresses. every party is different, thats what makes it fun. maybe theres a gamecube. maybe theres football. maybe people dance (usually they dont at the parties i go to, thank god).
as long as you show dome basic interest in the people there youre golden. you can even tell them its your first party if theyre nice, theyll look out for you.

you will notice that the alcohol carries the entire thing by itself.
oh and dont mix weed and alcohol.

Oh okay, but you aren't full blown asperger if you can understand the concept of what other people think about you. But let's say you aren't neurotypical.

People go to parties at a time (evening) where the mood is less inhibited. People drink alcohol and socialise. They do NOT want to talk about work/school/money and want to have casual, playful and funny interactions while talking about themselves. The "do you often come here" or "how do you know X? <- the host" are great conversation openers, because it is appropriate in the context. "What do you think about X?".
They drink alcohol to be less inhibited, and sometimes a bottle can serve as a totem for self confidence. People will avoid talking about negative and non-exciting stuff like politics.
Since you cannot play tennis, you might want to dance to show that you are in tune with the others dancing.
Parties always end up in unexpected events which are repeated over and over again for many years and create experiencial binding between the protagonists.
People don't expect you to do or be anything during a party. Just do not ruin the party for the others, try to follow what they are doing.

If your gf invited you to this party she knows you're good enough.

If the party is not like a party hard kind of meeting, you can always suggest walking outside for a location for no resonably good reason, playing group games that promote interactions, tell that X should get drunk, start asking others their astrological sign (works all the time), start juggling with anything, tell that you will do A if others do B.

In a party with your gf, ALWAYS side with her during arguments, tell only good things about her, and you're good to go!

>>18397545
Do people always get in arguments at parties?

>>18397554
Nope, but sometimes alcohol make people stupid, and they will argue about which fast and furious movie was the best. But if someone tells your gf that she is wrong, do not side with this person if you don't want to publicly betray her.
