hold - An informal practice by which a senator informs his or her floor leader that he or she does not wish a particular bill or other measure to reach the floor for consideration. The majority leader need not follow the senator's wishes, but is on notice that the opposing senator may filibuster any motion to proceed to consider the measure.
