I have some details that could supplement the outline.

Just for reference. Talk and socialise genarally take up anywhere from 80-95% of total time spent at parties. Generally most other activities include socialising even though they're structured. Beer pong you talk about beer pong and/or make fun of people's throws as well as just regular talking.

For neurodivergent people I recommend searching areas with fewer people, smoking is very convenient in those situations for a break between 3 sets of talking 10 minutes. Alcohol really helps too since it removes some of the talking friction. Dancing is also a good option since it's less talking and is a structured activity that's well received at most parties.

I enjoy parties as a charge of pace and getting rid of loneliness for example. Talking to friends and ignoring the rest is also fun but parties are exhausting imo.
