Part of it is self reflection at the realization they've become that disgustingly fat. The next part is having to pull themselves up and maybe make sure they didn't shit their pants. More than a few people talk about that happening to obeasts when they fall. Especially the fat fuckers who bully their way into those adult activity parks with the foam bits, trampolines, & ropes if its higher end. The people who had to deal with this tell of having to call emergency rescue services to get the butter huffers out of those. The one was pissed because the fat fuck had fallen and sunk to the bottom where he pissed & shit his pants.
