Narrative:
We both understood that we were cleared for visual approach runway 33L at bwi. First officer read back 'cleared visual approach runway 33L.' after our left turn direct to the OM for runway 33L at bwi, controller asked where we were going. We said 'cleared visual runway 33L direct to OM.' controller said we were to expect visual approach runway 33L, but not cleared for it. We got a turn about 45 degrees to the right for about 4 mi then cleared for visual approach runway 33L at bwi. We didn't think we did anything wrong at all. But the controller did.
