'Bashing' someone in a car then claiming it's their fault. You then win the case and get cash for it, this being the cash bash. Also called the grab-a-grand.

After getting into an accident, the victim(s) will fake symptoms more severe than they really are in order to gain more compensation for their "injuries".
A woman was discovered with what was thought to be whiplash. One witness knew that she was faking it as she was acting differently to other cases of whiplash and told the other witnesses it was just an attempt to gain "bash cash".
