Why do people say Jupiter is where you get stupider?

The phrase "Jupiter is where you get stupider" is often attributed to the planet's association with being large and chaotic, reflecting a sense of confusion or lack of clarity. Additionally, in Astrology, Jupiter is linked to excess and overindulgence, which can lead to poor decision-making. This playful saying highlights the idea that the planet's traits could metaphorically lead to foolishness or irrational behavior.
