Smashup is formed from "smash" (originating from the late 19th century, meaning to break or crush) and "up" (a preposition indicating direction or completion). The word "smashup" refers to a combination or mixture that results from smashing things together, often used in contexts like music or media.
Imagine breaking things apart ('smash') and then putting them together in a new way ('up') — that's what a smashup means.
