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.
I don’t know about people, but for me, in the parties I attended, it was various mixes of talking, drinking alcohol, eating, playing games, listening to music, and dancing. No activity was mandatory. Usually there’s always talking, drinking and alcohol, the rest depends on the party.
