AITA for making a joke with my mom and telling my friend about how it went downhill?

Yesterday, I was on a road trip with my family. I was really looking forward to it because we were going to Connecticut to go to some stores and I would get to shop with my mom, which I don’t get to do often. Anyways, we got to Macy’s which was a part of a big mall. Up until then, everything was going well and I was goofing off with my mom and we were having a good time. As we were stepping out of Macy’s and into the mall, my mom told me she was going to be joining a prayer meeting for a half hour and said she couldn’t talk during that time. We’re both Christian, so this wasn’t new to me, as I understand that it’s hard to listen to two people at once when you’re in a meeting. I also understand that her faith is important to her, as it is also important to me.

When she told me, I said, "Aw man, we usually never get to talk when we’re at the store" but I made sure it was in a silly tone, not in a angry or upset tone. I do admit I struggle with tone interpretation and how I express myself through tone, but I made sure that my tone was positive rather than negative. I even had a grin on my face. My mom replied by saying, "don’t be like that, you know I take the things of God very seriously," and said some other things. I started to freak out because her response was negative and I wasn’t fully serious and I already knew what she told me.

Anyways, I hurriedly said, "oh no, I didn’t mean it that way, I was joking!" Then she said I wasn’t joking and I kept explaining that it genuinely wasn’t serious to me at all and that I really didn’t mind and that it wasn’t a big deal to me cause I was genuinely freaking out so bad. Anyways, she goes, "stop or get the hell away from me." I stopped in my tracks and walked the opposite direction, back to the car. On my way back to the car, I sent my friend a message about what happened because I was honestly so shocked at what happened. Once I got to the car, my dad made me give him my phone and asked if I told anyone about what happened just now. I said no because I thought he meant was I texting them while in the car cause I was on my phone in the car before he made me hand my phone to him. He said I lied and I explained I did reach out to a friend when I was still inside.

Anyways, he told me I was a liar and that he can’t trust me because I talked about what goes on with my family to my friend and that I must keep my phone in my bag for the rest of the trip. It was a three-hour trip, so I was genuinely bummed. My mom came back and she was saying that I was letting the devil use me by making her upset before her prayer meeting and how I kept going on when she was about to join. I tried to explain how it wasn’t how I meant it at all, but it was no use. My dad told me that they never have any issues like this when I’m not with them on trips. I have such major regret for saying anything, God, I wish I could go back in time and just not have said anything and maybe things would have been better. Am I the A-hole?
