Use your mouth to talk

I went in a room supposedly about Britain in Skypeland but the host was not present. There were a large number of Arabs in the room, and someone or several people were making large farting noises into their microphones. At the sound of each one, people laughed. Finally one man said, in heavily accented English, "You Arabic people making noises with the ass. Go to toilet. Go to poo. Use your mouth to talk, not the ass".
