Sledging from the crowd!!
From Cricinfo:
Message of the day: And just when Graeme Smith thought it couldn’t get any worse. Two South African fans, shirtless and no doubt fuelled with lager, took out a banner soon after lunch. “Smith: Hope you’d scored more with Minki [van der Westhuizen],” it said, a reference to his former girlfriend. So much for not kicking a man when he’s down, and out [for 5].
And you thought the Aussies were bad!!
