In the context of insurance, this refers to adding vehicles to your car insurance policy or obtaining an additional policy to supplement your existing coverage.
Insuranceopedia Explains Pyramiding
Registering additional vehicles to your car insurance or purchasing a similar policy to cover the same vehicle is known as pyramiding or insurance stacking. However, this practice is prohibited in some U.S. states. Drivers with more than one vehicle in the household can get a similar benefit legally through multi-car insurance options, which cover several cars under a single policy at a combined rate.
