Duff
Duff means ugly, undesirable, or low-quality, and it can also be used more loosely for someone giving off bad vibes.
In use, it is usually a blunt put-down: a person, outfit, photo, or situation that does not look good to the speaker. The social read is pretty harsh, so saying it out loud can make you sound cutting, joking, or openly rude depending on the room.

What People Mean When They Say Duff
The core meaning is simple: duff = unattractive, unpleasant, or not worth the hype. In a lot of casual speech, it lands as a straight negative label rather than a clever insult.
It can describe looks, but it also stretches to energy and quality. A bad selfie, a grim outfit, a boring plan, or a person acting off can all get called duff if the speaker wants a quick dismissive label.
Where You'll See Duff
You are more likely to see it in messy group chats, blunt banter, or older internet and UK-leaning casual speech than in polished public posts. It is not a soft word, so people usually use it when they want the insult to land fast.
Because it is so plain and negative, it does not add much cool factor. It mainly signals that the speaker is being judgmental, not witty.

Is This Still Used?
Duff still shows up, but it feels limited and a bit dated compared with newer insult slang. It can sound natural in some UK or older internet circles, but in wider online use it is more likely to read as random, old-school, or unintentionally funny.
