In jail, when the policeman walks around the pod checking in every cell, inmates yell "one time" to alert the other inmates that the police are doing their rounds. This allows people smoking, drinking, etc. to put away their contrabad before the man arrives.
'ONETIIIME' shouted the inmate to his brothes smoking squares in his cell.
