often it's said to say it like a "hi" like "oh hey man, what you doing here?". It's a way to start a convo with many peeps, i use it too at some point, so it's usually not meant as a bad thing, but more or less like "oh yo what's up, how you doing?"

 

Hmm, that's an odd opener, I think.

In my mind, I'd take that as "Oh, someone invited you to a party?" or "I didn't expect to see you, a.k.a, you're not popular enough to be invited, you must have crashed, who did you come with?"

You're also right that there are people who know my aversion to social interactions that might be surprised, but when I've had the courage to show up at a happy hour or an office function, they're usually happier to see me because I did.

Perhaps @TheAsianSensei is correct and it's an innocuous icebreaker, but my brain wouldn't see it that way.

 

Ask them the same thing.

 

Well, do you go to parties where you don't know anyone or more like you were invited? Hmm, depends, but if you stand against the wall like a wallflower I guess them asking you that would be rather plausible. But still when they ask you what you're doing here they're being rude to you so you have all the right to return the favor! I mean what are they doing there but bullying others and being rude? Maybe they asked you that cuz you're on the wall instead of eating free samples and dancing around or talking to cute girls or making out with them in his room? So, if you don't want to be asked those questions then you know that all you have to do is what all the others are doing, just join in and do the same stuff they are. If you're just being a wallflower and doing something so different than the rest then of course someone's gonna notice and start bullying you. If you're a wallflower then just go where you feel comfortable or go to parties and get ready to get bullied.

 

You gotta just pop off on them in a situation like that. Tear off your shirt and ask them repeatedly if they wanna fight you. Trust me, it's the only way. I was a normie spy for years, you learn these things.
