So, you've managed to crash a party. Congratulations!
Arrive uninvited, but not unnoticed. Make sure to wear something that screams "I'm a functional adult, but also a hot mess."
Grab a drink, but not the last one. You don't want to be "that guy." Also, try not to spill it on your shirt. That's just embarrassing.
Be friends with the people who didn't invite you. They're the ones who'll let you stay for an extra hour.
Take over the conversation, the karaoke, and the snack table. Just remember to leave a few crumbs behind, or you'll never get invited back.
