Getting yourself ready to groove at concerts by moving to the beat in your head before the show starts.

Similar to pre-gaming, but not with alcohol, just groovin' vibes.

Just groove to the beat.
Non-groover: Yo man. I saw you groovin so crazy tonight. How do you groove so hard? All I did was just bob my head and stand still.
Groover: You know man. I was just pre-groovin' in the lot and on the way walkin up to the show. Just gotta find the beat keep on groovin'.
