The word 撒野 is formed by combining the character 撒, which means to cast, release, or let loose, with the character 野, which means wild, uncivilized, or unruly. Together, they create a compound where 撒 acts as a verb indicating the action of unleashing, and 野 serves as the object or state being unleashed, resulting in a meaning that literally conveys "to cast wildness" and denotes behaving in a unrestrained, rude, or insolent manner.
