Since I didn’t see any responses that directly answered the question of what do you DO, I’ve prepared a short guide for a generic social gathering. This guide may be inappropriate in some contexts such as a dinner party or event/tv show watching party, etcetera:

1. Show up

• Not at the exact start time, but at a minimum of 15-20 minutes “late”
• Bringing an unopened bottle of wine or a 6-pack of beer, or another drink of choice is almost always a classy move.
• If you drove, don’t park like an asshole. Consider the neighbors.
• If you’re standing on the doorstep and you can hear music, it’s probably safe to just walk in (make sure you’re at the right place!). Otherwise, knock/ring doorbell.

2. Party!

• Get yourself a drink and/or a plate of food if snacks are out
• Find friends and say hi! You should probably know at least one other person. How else would you have been invited?
• Explore! Hosts expect people in their house so it’s generally okay to look around, admire artwork, investigate the music, go into the backyard, etc. Don’t go anywhere that’s obviously closed off, unlit, or otherwise not a party locale.
• Talk and socialize. Meet new people! Ask your friend(s) to introduce you to their friend(s). Lightly eavesdrop on convos for something interesting you can talk about. Listen in general. Ask people what they like to do. Share stories about yourself! Pro tip: the length of your stories should be proportional to how well you know the person you’re telling it to. Just met the person? Suuuuper short stories. “No way! That reminds me of the time my cat was in the bathroom when she got hit by a car! The vet said she was very lucky to have a good friend!” (Confession: I used autocomplete to write that story)
• Dance!
• Find the host and complement their place, the party, the music, food, whatever. Just be nice. Offer to help if they look at all stressed.
• Play party games like beer pong or whatever.

3. Leave! Say thanks. Take your stuff. Cleanup whatever plates/glasses you’ve used. Don’t drive drunk. Don’t overstay your welcome.

This was probably too much info. I have insomnia. I hope someone reads this.

The reason I like lemmy, and reddit before, is that it feels like a cocktail party. You wander into a conversation already in progress, listen awhile, maybe say something, maybe make a new human connection.

Is that you, Zuckerberg?

You basically hide in the kitchen with the other kitchen hiding people until the party ends, particularly when someone in the living room picks up an acoustic guitar.

You can either walk around and talk to people (most people are receptive to being spoken to) or nervously hold your drink in hand, as you wait for someone to approach you.

Personally I prefer the former. If I’m by myself I just look for someone who seems nervous and uncomfortable. I’m friendly, and as long as I’m in a good mood I tend to make people feel comfortable around me- but I have had times where I just stand there. Standing and waiting is highly unpleasant. Better to hide in the bathroom if that’s what you’ll be doing instead of chatting. Highly recommend chatting or “mingling”

(If someone is lame, boring or seems uninterested, just approach someone else. Most groups will also make a space for you if you approach them in the event that there are no loners)

It starts by inviting your core friend group over an hour early for pre drinks. You and your friends drink and put some music on and as people arrive you integrate them into whatever you’re doing. As more people arrive and everyone gets drunk people break off and chat, dance, play games

If you’ve ever been to a festival or fair, think of it as a miniature version of that. It’s mostly just a hangout for people to do fun things they wouldn’t do everyday, since they feel the day is exceptional.

Drink, get hit on by girls that want to know why I’m so quiet.

I think stay home and get drunk by yourself. It’s the only way to guarantee you won’t say something slightly embarrassing and then dwell on it for the next week

Most of the parties I go to are typically just chatting and drinking/smoking. Good way to meet new people that likely have similar interests to you, since everybody there already has at least one common connection, usually. Activities will depend on the friend group. Some of my get-togethers will have a light-hearted board game, sometimes everyone will watch a movie and riff on it MST3K-style, sometimes we’ll just get high and bitch to each other about work.

Personally, I don’t really go to parties where there’s music or dancing, since that’s not really my scene. But sometimes the mood will just be right and someone may crank up some tunes and start moving.

It really varies depending on your personal circles. If you’re invited and feeling anxious about it, just go with no expectations. Just show up, hang out, chat a bit, and feel things out. If you decide you don’t like it, you can always just leave, and usually nobody’s gonna care.

Most just talk to people

Look at my watch and wonder when it’s socially acceptable to leave.

Some great responses but not one (yet) mentioning attempts to hook up in some way? For me that was the whole point of going. To either play with some pussy that night or set something up for the future.

Edit: Being downvoted for chasing tail at parties? I must be getting old because I do not understand the younger generations at all.

People say “party” but really it is an awkward conversation generator. Unpleasant.

I get bored easily, so I bring instruments and play along with the music or the other musicians. Or, increasingly, I am the music.

I also bring my spindle, or my sewing. Or I stand around the kitchen helping with the food. Find a thing you do well, whether it is barbecuing skewers on the hotplate or pouring drinks, and then it will be a thing to do with your hands making for less awkward. Be helpful. And don’t get too drunk because drunk people aren’t as awesome as they think they are.
