Makes sense, thanks. I guess it would only feel like a slant if the "force" causing the odd shape, the gravity of the pulsar, was removed. Then all the extended gas would fall back towards the center, while a solid planet might be able to maintain its odd shape. Then that pointy end would be like a giant mountain, in terms of how it would feel to be on.

Now I'm wondering if the planet is tidally locked, otherwise the forces on the extended and retracted bits of the lemon would shift widely as the planet rotates. Actually we could then model the extended bit as a giant tidal wave, er, tidal cloud. What a world.
