An condition where your thoughts are jumbled and your brain is just generally not functioning well. This is metaphor comparing the unorganized thoughts to food items floating about a soup without any direction. This is often caused by overworking yourself, having a hangover, or something similar. It's comparable to being brain dead.
Guy 1: How are you feeling this morning man? You were pretty messed up last night.
Guy 2: I have brain soup right now, I can hardly even think of a way to respond. Don't let me drink that much again for at least two weeks.
