throw in your lot with someone

COMMON If you throw in your lot with someone, you decide to join them and to share whatever good or bad things happen to them.

Note: People sometimes use cast instead of throw in. I cast my lot with him through those long, difficult years. Note: In the past, `lots' were objects such as pieces of straw or paper which people used when making a decision or choice. Each lot represented, for example, a different piece of property or course of action. All the lots were put together and then chosen at random to decide who would receive the different pieces of property or what action would be taken.
