Read the explanation below to understand the nuance of how this grammar structure is used.

This is about time, or a situation, slipping by you. You were busy, you were focused, you were hustlin’, and when you finally looked up, everything was different.

Metaphor: This is like waking up from a daze. You’re so focused on the hustle, on making the beat, on the fight, that you don’t notice the world changing around you. When you “wake up,” you’re like, “Damn, when did this happen?”
