spill-over bill
n.— «One of the rites of passage for legislators is a vote that occurs near the end of each legislative year on what is known as the “spill-over” bill. This is a massive spending bill that is used as a way to dole out extra taxpayer dollars in order to placate those who did not get everything they wanted in the yearly budget.» —“Violating the Constitution” by Jason Murphey Edmond Sun (Oklahoma) Feb. 18, 2008.
