when you walk into any house party, and you can clearly tell you will have a good time due to the volume of people and beer, you walk into the party scene.
(taken from All Time Lows song, The Party Scene)
Jack and Jill walk into a house party
Jill says "holy shit theirs a lot of people in this bitch, and like 6 kegs"
Jack replies "This is the party scene, I'm getting laid tonight"
