It could refer to Poe altering or skipping proper lightspeed calculations causing the Falcon to be damaged on the jump to hyperspace. Either way it’s just nebulous technobabble without the actual skipping scene.
FWIW, this is how it would read to me too. Poe is about to do something crazy to escape, Chewy reacts to it, the Falcon bursts through an ice wall into hyperspace. It seems like that would be enough to damage the Falcon and justify an argument with Rey about it. The “skipping” part would just sound like random technobabble to me.
Yeah, my only issue with that currently is that the Falcon looks perfectly fine when it bursts through the ice wall, making it seem like the damage occured afterward.
