I love sweet and gentle stormpilot as much as everyone, but Finn and Poe are both incredibly passionate individuals with (I imagine) a wide variety of separate interests. This leads to bickering, nothing serious, mostly playful with snarky!Finn giving as good as he gets. But they've built quite a reputation around the base now for their constant and increasingly passionate debates and disagreements, which start out in normal tones over lunch and end up with them both loudly addressing the cafeteria at large for a vote to determine who's right. It's getting ridiculous.

Bonus if this is before they're together and one especially passionate/annoyed argument leads to making out and them becoming the (still argumentative if a little gentler) Stormpilot we all know and love ^.^
