Made beautiful; embellished or enhanced; or having been called/treated as 'beau' (a romantic partner or suitor).
From 'beau' (beautiful person, romantic partner) + '-ed'. A rare or non-standard formation; could be playful English word-making.
This is likely not a 'real' dictionary word but rather shows how English speakers playfully make verbs—if you can 'flirt,' why not 'beau'? It's the kind of word that might appear in literature or casual speech but wouldn't be in standard dictionaries.
