Tits up! 

shoulders back, stand tall, walk with purpose.
Used frequently in the TV show Marvelous Mrs Maisel.

When you catch yourself allowing your inner critic to run rampant, pull your shoulder’s back, say tits up! then stand up and roar.

Tits up 

Expression to describe when a person or activity has run its course and met its end. Dead. Finished. Done. The expression is thought to have originated from military pilots when reporting from the air the visual status of other planes that had gone down and met their end, and in doing so on the way down or at their final resting place (or both), were often times "upside down" with their wheels pointing up rather than down as they operationally should have been. When seen from high above upside down with belly and wheels pointing up, they were described as they appeared....."tits up".
