The official battle cry of Wyoming athletics, the university of Wyoming at Laramie.

It literally means bring on the bronco and let her buck, but figuratively it means to bring on a challenge and let it throw you around while you try to conquer it.
Let 'er Buck, larry!

Son, you just gotta Let 'er Buck and git 'er done!
