Why not just say cheating? Looks like we have another imbicile in the team.
Red handed: Cameron Bancroft charged with ball tampering, Steve Smith admits complicity

Cameron Bancroft is spoken to by umpires.
AUSTRALIAN opener Cameron Bancroft has been charged for ball tampering after being caught red handed using a foreign object to alter the state of the ball before attempting to hide the evidence.
In further bad news for Cricket Australia, captain Steve Smith confessed to being complicit in the tampering in an explosive post-match press conference that he fronted alongside the embattled opener.
Bancroft was shown rubbing his hands over the ball with a concealed yellow object shortly before tea on Saturday.
Soon after umpires Nigel Llong and Richard Illingworth met mid-pitch. As this was happening Bancroft took the yellow object, which he later stated was tape he was using to collect dirt to deposit on the ball in an effort to encourage reverse swing, and hid it down his pants.
This happened after a conversation between Bancroft and 12th man Peter Handscomb who had entered the field of play. When questioned by the umpires, Bancroft satisfied them that nothing suspicious was going on by showing them his sunglasses case.
The ruse did not last long however, with Bancroft charged with ball tampering shortly after the close of play — a level two breach of the ICC’s code of conduct which could land him a Test ban.
