uh, well then, it's where like if you have created it or like if you've been invited and it lasts a period of time. For instance, a birthday party is when you celebrate someone's birthday and you can stay there and eat food and watch them open presents, and a party party, like a prom, would be like you go to a club or someone's house and hang out with your significant other or friends and/or eat more food.
i went into detail, that's the only other way i could explain 😟
