In a manner characterized by showy or frivolous ornamentation; excessively or tastelessly ornate.
From 'fallal' plus the adjectival suffix '-ish' and adverbial '-ly'. This rare formation describes doing something in the style of fallals—with excessive, superficial finery.
This word is so obscure that it's barely used even in historical texts, but when it does appear, it's always cutting—imagine saying someone 'decorated fallalishly' in a period novel, and you've just delivered 18th-century shade.
