Vastie is an uncommon given name of unknown origin. It appears to be a modern creation, possibly derived from various sources such as "vast" meaning extensive or widespread, or influenced by similar-sounding names like Vashti or Victoria. Vastie is primarily used as a feminine name but could potentially be used for males as well due to its unisex nature. As it's not a traditional name with historical significance, it doesn't have any specific associated cultural practices or traditions. The name first gained notice in the late 20th century and has since appeared sporadically in various countries, though it remains relatively rare.
The name Vastie experienced fluctuations in popularity over the early 20th century, with a noticeable spike in usage during the years 1918 to 1919 and again in 1926 to 1928, before tapering off after 1930.
