The phrase originated from the way birds, particularly peacocks, display their feathers to attract mates or intimidate rivals.
Here are some examples of how the phrase is used:
* "You look great in that outfit, go out there and strut your tail feathers!"
* "After winning the competition, she strutted her tail feathers all the way home."
* "Don't be afraid to strut your tail feathers and show everyone what you can do."
