Couldn't really tell what they were doing or said from the video. Couldn't really tell their nationality. Yes, one guy was wearing a sweatshirt that Central Park on it but that doesn't mean they are Americans.
"Taking the piss out of someone". It is British slang for making fun of someone/or mocking someone.
Just so you know, when me and my mates have been out on the piss all night.......it's not what you think!
I watched the video repeatedly and didn't see any unruly behavior at all. What's the protocol here? At 1:35 a woman petted Mr. Ed on the face for at least 10 seconds. The two kids seemed respectful throughout the interraction.
