AFTER David Warner accused Quinton de Kock of a "vile, disgusting" sledge about his wife in the first cricket Test between Australia and South Africa, some fans took it upon themselves to mock the Aussie opener's partner at the second Test in Port Elizabeth.
Rabada trapped Smith plumb in front in the 52nd over as the umpire raised his finger.
The on-field umpires Chris Gaffaney and Kumar Dharmasena charged Rabada with making physical contact with Smith, but South Africa have indicated they will contest the charge on the basis that contact was accidental.
The hearing will be conducted by International Cricket Council match referee Jeff Crowe. The perfectly-flighted delivery dropped just short of the South African star's bat and whizzed past him to collect his off stump. He put on 30 for the ninth wicket with Lyon and then 31 for the final wicket with Hazlewood.
The two officials, former Test star Clive Eksteen and communications manager Altaaf Kazi were scolded for their involvement in the charade which prompted a hasty apology from Cricket South Africa.
Smith made it clear last month that he was well aware of Rabada's disciplinary record, noting "it could perhaps be a plan to try and get him fired up" and "you never know what some guys do when they're fired up".
Rabada was a highlight of the day's play, claiming his eighth five wicket haul in his young career.
Markram has already been lost in the response with Pat Cummins trapping him plumb lbw for 11 shortly before the close leaving Dean Elgar and night-watchman Rabada to see out the remaining overs of the day.
New footage shows the pair walking from the ground together and Warner is heard to call De Kock a "fucking sook", according to The Australian newspaper, referring to someone who is soft or easily upset.
Rabada finished with bowling figures of 5-96 while the 21-year-old Lungi Ngidi, who was a surprise pick ahead of Morne Morkel, took 3-51 including bowling David Warner for 63.
In reply South Africa were 39 for the loss of one wicket at the end of day one.
From the second session it was a different match, Australian middle order crumbled against the swing and speed of Philander and Rabada.
Mitchell Starc (8) was Rabada's fifth victim, clean bowled to leave Australia reeling on 182-8.
Tim Paine, however, frustrated the home side by scoring 36 runs as Australia added 61 runs for the last two wickets.
