Grant Teacher's Answer:
Hi Tin,
"hurry up" is a command used more like a verb than an adjective.
You can say "Billy, hurry up and give me my hat...I'm freezing!"
But you wouldn't say "Don't be hurry up."

You could say "Don't hurry up."
But it is not that common. You would usually just say "Relax." or "Slow down." or "Take it easy."
