"Hath fling" is an archaic phrase that has fallen out of use in contemporary English. However, there are several synonyms that can be used to convey similar meanings. One such synonym is "have thrown," which can be used to indicate that someone has launched or hurled something. Another possible synonym is "cast away," which suggests that something has been discarded or disposed of. "Pitched" is another term that can be used to describe throwing or tossing something forcefully. Alternatively, "flung" or "tossed" can be used to describe a rapid, forceful throw or toss, while "lobbed" suggests a gentler, more deliberate throw.
