dynamite

This term carries a heavy connotation of sudden, violent destruction and immense power. While it refers to a specific chemical compound, it is frequently used in a figurative sense to describe something explosive, exciting, or highly effective, such as a dynamite performance or a dynamite personality. As a noun, the word is uncountable because it refers to a mass of explosive material. It cannot be pluralized to describe multiple units of the substance; instead, speakers use partitive phrases like a stick of dynamite or several bundles of dynamite to quantify it.
