Honestly, what can I do?

Okay so I went to my friends house with a few of my buddies, there was me, my boyfriend, 4 other guys, and 1 other girl. I was honest with my mom and said there was gonna be a few drinks here and there, but I didnt have a drink because she didnt want me to. So anyways, I was at my friends house, there was a parent there, and I also had a ride home by my boyfriends mom at 12. So my boyfriend called his mom at 12:15, and told his mom the directions to the house. At 12:15 my mom shows up at my friends house. I get in the car, and my mom starts yelling at me, asking why I didnt pick up my phone, which was because it didnt even ring, because there was no reception in the basement, and when I told her that she was like “ yeah okay whatever christine, you an inconsiderate b*h, and you dont appcicate anything, and those friends of your are all trouble, and that boyfriend needs to go for a flying leep (whatever that means)”, I honestly didnt know what to say, and than she starts telling me that im only 16 and shouldnt be out at 12:30, 1 at night, but I dont get it, I mean like I was at someones house, which a parent home, and I also had a ride home from someone that she knew, like I would understand if I was like out and around like in the town, but at somones house, with a parent home, having a ride home by the person my mom knows, I just dont understand. What should I do, I dont know if shes mad, but I was also suppose to go to a friends house tomorrow, my bestfriend, who I havent seen in over a week, so, now I think im not gonna beable to go to her house, for a reason I dont even know.
