I remember something similar happened to me. I attended a party with friends and decided to bring a car. Eventually a lot of my friends started teasing, and is pushing me to drink, but I just didn't mind them. What I ended up doing though was eating a lot of the food while they drank a lot. A family member had an accident with a drunk driver, so I know the risks, and I try my best to keep safe.
Assholes.
It wasn't as bad as your experience, since they're my friends. But yeah, a lot of people tend to want others to drink or keep on drinking as long as they are.
