A filibuster is a parliamentary delaying tactic. It is typically employed by opposition parties to delay or prevent the passage of a bill they don’t like. A filibuster is brought about when legislators speak at great length in opposition to a bill; propose numerous, often trivial amendments; or raise many parliamentary points of privilege. All of this is designed to keep the bill from coming to a vote. The goal of a filibuster is to either change a bill or stop its passage.
