The tactic of deliberately delaying or obstructing legislation through prolonged speeches or procedural maneuvers; or the act of engaging in unofficial military adventures.
From filibuster + '-ing', present participle form. The modern legislative meaning developed in 19th-century American politics as the term evolved from its original pirate reference.
The most famous American filibuster lasted 24 hours straight—Senator Strom Thurmond talked without stopping in 1957, reading from cookbooks and telephone directories because he'd run out of actual arguments.
