The term for someone spending 20 years in the 24th row of a theater is not widely recognized or established in a specific way. It seems to be a play on words or a joke. However, it is important to note that theater seating and row numbering may vary, so it's possible that this particular reference may be specific to a certain context or a joke within a particular group or community. It is always helpful to provide more information or context if you have it, as it can aid in understanding certain references or terms.
