A crushing defeat is a devastating loss, usually in a battle or competition. In this case, the term CRUSHING DEFEAT can be broken down into three words: WATERLOO (8 letters), ROUT (4 letters), and OVERTIMELOSS (12 letters). WATERLOO was a famous battle in 1815 where Napoleon Bonaparte was defeated by the British and Prussian forces, resulting in his exile. A ROUT is a complete defeat in which one side is completely overwhelmed and forced to flee. Overtime loss is a term used in sports, referring to a game that has gone into overtime and ended with one team losing. All together, these three words paint a picture of a total and utter defeat.
