Do you mean the moments leading up to the fight?
From a story stand point, there are a few options.
1: "Wild West" : You have tension building in the scene. Like in a wild west movie. Establishing shots, showing tense expressions, reaching for their weapons. Then a sudden action from the aggressor.
2: "That escalated quickly" One word can set off this scene! Causing it to quickly transition into a fight.
3: "Flashback" Characters reminiscing on the past and a hard cut to the present, they're fighting!
Thats all I can think of right now, I'd suggest a simple formula: Tension > First move > Second move
If someone is thrown they can have a dramatic panel of getting up and getting back into the fight.
You can also incorporate SECRET MOVE!! inner dialogue.
