Meaning & Origin
Frosty is a boy's baby name of Old English origin, derived from the English word frost, from the Old English forst or frost, referring to frozen water crystals or a sharp cold. As a name, it carries associations with winter, crispness, and the cheerful cultural image of Frosty the Snowman, the beloved 1950 holiday character.
Frosty is exceptionally rare in U.S. birth records and has no national ranking. It belongs to the tradition of American nature-word and nickname names — names that carry a vivid sensory image rather than a classical etymology. Its seasonal associations make it a distinctive choice for a winter baby.
