A false eyelash, typically made of synthetic hair or natural fibers, worn to make eyelashes appear thicker or longer.
From 'false' + the diminutive suffix '-ie' (colloquial). Emerged in mid-20th century beauty industry terminology. The shortening reflects how cosmetics marketing creates casual, friendly terms for beauty products.
The term 'falsie' perfectly captures how language evolves in pop culture—a technical cosmetic product gets a cute, informal nickname that makes it less intimidating and more fun, much like how 'selfie' transformed photography vocabulary.
