Worst in what sense?

One time I was in the back row of mini J on a 77L, chatting with a friend.

A passenger yelled at us to keep it down.

My friend shouted "okay 10K, okay I'll try to keep it down, okay 10K" and more at the end of the flight when 10K didn't have her seatbelt on.

Then there was beer pong in J, but no one seemed annoyed by that
