A man has his foot on a womans head under the table at a dinner party

I was at dinner with my girlfriend and her friend when the guy I knew as a friend put his foot on my girlfriends head under the table. I asked him why and he said it was a joke. It was not funny and I was very uncomfortable. Is it wrong for me to be uncomfortable?<br><br>What's your take on this?<br><br>I don't think the foot was on the head the whole time, maybe for like 10 seconds, I don't know
