What does it mean to say “that’s enough onion for the day”

The phrase "that’s enough onion for the day" is often used colloquially to suggest that someone has had enough of a particular experience or situation, especially if it has been overwhelming or emotionally charged. The use of "onion" can metaphorically refer to layers of complexity, emotions, or issues that can be peeled back. Just as one would not want to overindulge in onion due to its strong flavor or potential for causing discomfort (like bad breath), the expression implies a need to take a break from something intense or heavy. It can also suggest a desire to lighten the mood or move on from a serious topic. This expression may not be universally recognized but can be interpreted based on context and tone.
