The phrasal verb underlined in the song means:  

Read the text and answer the question.

On top of the World-Imagine Dragons  

If you love somebody

Better tell them why they’re here cause

They just may run away from you

You will never know what went well

Then again it just depends on

How long of time is left for you

I’ve had the highest mountains

I’ve had the deepest rivers

You can have it all but not til you move it

Now take it in but don’t look down.
