stick your chin out
stick (one's) chin out
To show resolve, determination, and fortitude. Despite the team's performance in recent years, their star player has shown a remarkable amount of character by sticking his chin out and publicly reiterating his commitment and loyalty to the team. It would have been really easy for the manager to just follow to the board members' instructions to the round of layoffs, but instead she stuck her chin out, protested and fought for the rights of her team, and in the end managed to keep their jobs.
