The act of becoming one with whatever task you are trying to achieve. One dimensional. Tunnel vision. Grindin'. One who is "in my bag" has forgotten about all else except for the current moment. When you are in your bag you are unstoppable, you will shred anything and everything.
I was in my bag when I got 30 headshots last night!

the act of being in your own world; focused; being in the zone; on your grind
