Murray, Labour MP for Edinburgh South, told Forde the description “sounded like a full council meeting”.
He pointed out that football fans are prohibited from drinking in stadiums during matches but the same rules do not apply to rugby fans.
Murray was previously chairman of the Foundation of Hearts group, which bid to save Heart of Midlothian Football Club from administration in 2013.
He told Forde: “I think it’s snobby.
“I mean, Murrayfield is a great example. You can go and see Scotland versus the All Blacks on a Saturday at three o’clock and get as ratted as you want sitting watching the rugby, and people do, they spend most of their time at the bar.
“And I remember my team, Hearts, played Celtic there the following day on the Sunday, when Hampden was out of use for the Commonwealth Games, and there was a complete ban on drinking in the stands for the football fans. That’s just classist and snobbery.”
Asked if he wanted to bring back drinking at football stadiums, the Scottish Secretary joked it was either that “or not have rugby drinking”.
