The term 'FROZEN SPIKE' can be broken down into two words, 'FROZEN' and 'SPIKE'. The first word, 'FROZEN', is defined as something that has been made solid or immovable by cold temperatures. The second word, 'SPIKE', is defined as a sharp point or projection. When combined, the term 'FROZEN SPIKE' can refer to a sharp point or projection that has been FROZEN in place due to cold temperatures. An example of this would be an icicle, which is a FROZEN SPIKE of ice that hangs from a roof or other surface.
