If you are really tired, as in exhausted, you can say that you are “pooped” or “pooped out.” “Pooped” or “pooped out” means you are very worn out and exhausted.
– I’m pooped! Can we rest for a while?
– Sam was so pooped out after the training session at the gym.
– Are you ok? You look pooped?
Be careful! You can say to someone, “you look pooped.” but not “you look like pooped.”
What makes you pooped out?
