I personally prefer lightspeed slipping. The idea being that a ship can enter hyperspace in order to “slip” past or through objects in real space. As long as the object doesn’t have a heavy mass shadow, like a planet or moon. So Poe was trying to slip past/through the ice wall, but called it a little close and damaged both the Falcon and the wall. Although it was still preferable to the alternative, which would’ve been just crashing right into the wall and blowing up. I did suggest both originally and made arguments for both, but I feel lightspeed slipping feels slightly more like authentic Star Wars lingo vs clipping imo.
But I think I have versions of both “slip” and “clip”, so I’ll send both to Hal.
