By "party", I mean a physical social gathering of people for the purposes of having fun. It may be used in a sentence as "I am throwing a party!" or "Let's party!".
Basically what I am trying to say is the default "party".
I've never been to any, and I have no idea how people spend their time on parties, so I am curious how you did.
You have a drink in your hand, you go “oh hey it’s Alex how have you been man?”
Alex tells you about his new hobby.
You gesture to your friend “hey Alex have you met Jamie?”
Alex and Jamie get to know each other.
Rinse and repeat.
Jamie meets a friend and starts chatting. You awkwardly stand beside Jamie taking sips of your beer until Jamie says “hey Andrea have you met my friend 420?”
You introduce yourself.
After a while everyone has met and had a few drinks and some good music starts playing and you start dancing in the dance floor. At first it’s very self conscious but after several songs and another drink you start vibing.
