A filibuster is a type of parliamentary procedure. Specifically, it is the right of an individual to extend debate, allowing a lone member to delay or entirely prevent a vote on a given proposal. It is commonly referred to as talking out a bill,[1] and characterized as a form of obstruction in a legislature or other decision-making body.

In other words, they can hold the floor until they stop talking. They can do this until the deadline to vote on the proposal passes. Great movie to watch about this is Mr Smith goes to Washington http://www.imdb.com/title/tt0031679/

Talk....talk.....talk.....talk....talk.... !

We have one every day at my place.

Stick around awhile you will be able to see one live in action in here at some point.
