moon the crowd

[Vladv1]

"There was one final ‘farewell’ Saturday night show at the old Bondi Wife Swapper, on 27 March, where Billy Thorpe got up to jam with them on the encore number, ‘Baby, Please Don’t Go’, and during which Angus did something for the first time that was to become another trademark move of his at all future AC/DC shows: he dropped his shorts and mooned the crowd. He also used the long bar as his personal catwalk, running the length of it while still playing before coming to a stop with a knee-slide that sent glasses flying left and right".
Mick Wall, "Hell Ain't A Bad Place To Be".

What does moon the crowd mean?

He displayed his bare buttocks to the audience.

It means: "to expose one's buttocks to an audience, often as a form of protest, insult, or jest" from the [COMMERCIAL APP NAME REMOVED BY MODERATOR] dictionary: [LINK REMOVED BY MODERATOR]
