straight out of the chute

Etymology
Taken from rodeo routines: the bucking bronco, or bull, or the calf for the calf-roping contest is kept in a narrow pen, a chute, before being released.

Adverb

 * 1)  immediately, from the very outset.
 * His ride on Bold Lancer started out just like he thought it would. The bull bucked straight out of the chute and slowly came around to the left. Clay remained in position, forward on his bull rope, spurs raking the bull’s side. It looked as if it was going to be an easy ride, albeit a low-scoring one. Bold Lancer had other ideas.
