Boos flow (bõõös flôw): The state in which an (animal) consumes too much of an unknown (unsafe) substance to their digestive system that leads to boos immunity, a stage that causes a dog to be so cute and humble that they no longer seem to be moving. One might say they died from their own overwhelming cuteness

An expression that describes a morbidly obese person's rolls of fat, usually, but not limited to, the torso of their body. Typically, these rolls of fat are spilling over pants, shirts, or any other articles of clothing, resulting in a visual analogy to lava flowing over a wall, embankment, or into a body of water.
