AITA for telling a girl if she wanted friends, she should n't use a pregnancy test as a bong?

I (17m) was at a party last weekend. I really didn't want to go, but I didn't want to seem like a dick so I went. I was in a really bad mood at this party and was sitting on a wall watching some people skateboarding. One of them was a girl. I guess she was 16 or 17 too. She was trying to do some cool tricks but was obviously not very good at it. I just sat there watching her mess up a few times.<br><br>When she had skated past me, she nocks her board against the wall and I jumped in shock. She laughed and said "You okay?!" I said that yeah, I was okay and that she had a lot of work to go before she could do any tricks. She laughed and I started to laugh too. I said she had a lot of work before she could even ride a skateboard.<br><br>She asked if I could teach her and I was about to say no, but something just came out of my mouth that I didn't expect. It went something like this;<br><br>"Why don't you try riding one under the influence first?".<br><br>She gave me a weird look and said it was a bad idea, then I said "Yeah, it's better to get pregnant than to get drunk and fall off." I know she had rode a skateboard under the influence because I had saw her use a bottle as a bong earlier. I think it was weed, I don't know.<br><br>I went back to my wall and she didn't bother me anymore.<br><br>I felt really bad for jumping at her and scaring her, but the way she laughed like nothing happened bothered me. Like it was no big deal that she had tried to get pregnant.<br><br>The next day at school some people were talking about how I told a girl if she wanted friends, she should n't use a pregnancy test as a bong. I was like "What the fuck are you talking about?!" I didn't say that. I don't remember anyone else being there so I assume she told them.<br><br>I apologised to her later that day and she said I had said something disrespectful to her face and that I was a disrespectful asshole.
