To really understand how a place works, first you have to speak the language.
Often shortened to â€œUC,â€ this term means that 100% of the Senators physically present on the Senate Floor agree to a pending request. Senators have such sweeping rights to Floor debate that unless 60 of them vote together to invoke cloture, a single Senator can hold up almost anything by refusing to grant Unanimous Consent. There are hundreds of Senate rules and procedures which are commonly waived by Unanimous Consent-- a classic example is the rule that every bill must be read aloud three times. If a bill is a few hundred pages long that would take a whole week-- effectively killing that bill.
