masher

The word 'masher' is a straightforward agent noun formation from the verb 'mash', which entered English from Germanic roots with the sense of mixing or crushing. The '-er' suffix, a common Germanic derivational tool, creates a noun denoting an entity that performs the associated action. Consequently, the primary meaning logically refers to a tool for mashing food. The slang sense, originating in late 19th-century American English, applies this agentive logic metaphorically to a man who aggressively "crushes" on or makes advances towards women, portraying his behavior as a clumsy, forceful action.
