'pincher' originates from the verb 'pinch', which comes from Middle English 'pinchen', derived from Old French 'pincier', meaning 'to squeeze or nip'.

'pinchen' transformed into the modern English word 'pinch', and 'pincher' was formed as a noun to describe someone or something that pinches.

Initially, it meant 'to squeeze or nip', and this meaning has largely remained the same in modern usage.
