What does festy mean?
"Festy" is an informal adjective used to describe something sour, rancid, or otherwise unpleasant to the taste or smell, and — especially in Australian and New Zealand slang — anything dirty, grimy, or generally off-putting. The word is chiefly regional: it has long been part of Scottish and Northern English dialect, where it applies most literally to food or drink that has gone off, and it travelled with settlers to become a familiar colloquialism Down Under, where its sense widened from taste to overall condition. Calling someone's shoes, kitchen, or gym gear "festy" is a blunt but often humorous way of saying they need a wash. Because it is colloquial rather than formal, it suits casual conversation far better than polished writing, yet its vividness makes it a memorable alternative to plainer words like "dirty" or "stale".

Etymology of festy
"Festy" originated as a dialect word in Scots and Northern English, where it was used of sour or rancid taste; its ultimate origin is uncertain, so no definitive root can be stated with confidence. The word spread through British emigration to Australia and New Zealand, where colloquial use broadened it from taste to general dirtiness or unpleasantness. Related-sounding terms such as "testy" and "zesty" share only the rhyme, not an established common origin.
How festy is actually used
"Festy" is informal and chiefly regional: in Scottish and Northern English dialect it traditionally refers to sour or rancid taste, while in Australian and New Zealand colloquial speech it has broadened to describe anything dirty, smelly, or off-putting.
