This is an allusion to a Randy/Avi conversation of two years ago wherein Avi actually calculated a specific numerical value for "fuck-you money." It was not a fixed constant, however, but rather a cell in a spreadsheet linked to any number of continually fluctuating economic indicators. Sometimes when Avi is working at his computer he will leave the spreadsheet running in a tiny window in the corner so that he can see the current value of "fuck-you money" at a glance.
