a word that used to mean innocent 8 year olds going to someones house with their parents as chaperons, usually for a birthday, doing organized things like playing twister, videogames, eating pizza or cake.
Once a child hits the age of 13, the word "party" then officially means to have a few people over to ones house when the parents aren't at home to get ridiculously high/drunk
Dude,mom just left, she'll be out for at least 5 hours. let's party
no dude, we're too old for that. i don't feel like dragging twister out of the attic or making a cake.
no you idiot! get the bag out of your room, let's light it up!
