One time some girl came up to me with her clique and they all looked really ghetto and hood and one of them claimed I stole her man

I didn't even know who her man was, I said I don't know him. Then one of her back up girls claimed she saw me sneaking out of his house. I have NEVER seen this girl in my life. I said I didn't and the main girl slapped me, saying I was accusing her of lying. Right now, I wanted to cry. She snatched my phone and forced me to put my password in and she went through my Instagram/Twitter and she couldn't find her boyfriend. She then accused me of hiding evidence and she punched me in the nose. Then, her boyfriend comes not even seeing the main girl and he kisses the girl who claims she saw me sneaking out of his house. Then the main girl and the girl who accused me of sneaking out of his house started fighting and stuff. I just took my phone and went home. It was really scary.
