I had to sit on my boyfriend's friend's lap? Please help me?

My boyfriend, his four friends, and I were all going to drive up to this lookout. The only car with 4 wheel drive was my boyfriend's so we went in his but I couldn't fit. All of his friends volunteered to have me sit on their laps and were joking around so my boyfriend picked the friend that he trusted the most. As we were driving I fell asleep (I fall asleep every road trip) in the crook of the friends neck and he was still holding me to him to keep me secure. I guess while I was sleeping his friends were talking about how we looked adorable snuggled up and my boyfriend was pissed by the time I woke up. He is still being a buzzkill. How can I make him stop being pissy?

To clear things up, my boyfriend had to drive because the rest of the guys can't drive standard. If they would have drove we would have wrecked.
