When senators give very, very long speeches to try to prevent a vote on a bill they do not want, this is an example of a filibuster.
1890 These duties involved prodigious physical and mental exertion, in a climate deadly to Europeans. They also involved much voyaging in waters haunted by filibusters and buccaneers. But nothing appears to daunt Labat. As for the filibusters, he becomes their comrade and personal friend; – he even becomes their chaplain, and does not scruple to make excursions with them. — Lafcadio Hearn, Two Years in the French West Indies.
