your friends invited you to an only girls party, little did you know they were lying about the “only girls” part

you entered the party exited, but soon your smile turned into shock. Your friends looked at you with a smirk. I mean, the only thing you could see where people making out, people getting drunk, or even flirting. You were mortified, you looked back at your friends and realized they were gone by the second you entered. What will you do?
