A filibuster is a parliamentary procedure where debate over a proposed piece of legislation is extended, allowing one or more members to delay or entirely prevent a vote on the proposal.
A tactic used by members of the Senate to prevent action on legislation they oppose by continuously holding the floor and speaking until the majority backs down. Once given the floor, senators have unlimited time to speak as long as they follow the Senate rules and it requires a vote of 3/5th of the Senate to end a filibuster.
