I don't get it. Why would you laugh at your family/friends when they're puking? What makes it funny? I think it's crap.
I also think it’s crap to laugh at their friends and family when someone is sick. I think the reason why they do that is because they wanna see how much puke comes out of their stomachs. People are certainly interested in when their friend/family member pukes and it comes out like a geyser.
The sounds and sights of vomiting make people laugh. For example, if someone had just eaten a large meal, and they throw up, sometimes it ejects out of them like a violent waterfall. That is mainly the reason why people laugh at others when they’re vomiting, because it’s how much vomit is coming out of the body.
