upstage
at or toward the rear of the stage
the dancers were directed to move upstage
steal the show, draw attention to oneself away from someone else
When the dog entered the stage, he upstaged the actress
aloof
distant
remote in manner
stood apart with aloof dignity
a distant smile
he was upstage with strangers
move upstage, forcing the other actors to turn away from the audience
of the back half of a stage
she crossed to the upstage chair forcing the lead to turn his back to the audience
treat snobbishly, put in one's place
the rear part of the stage
