I recently read on the internet (where else?) that some people get upset with some other people that use the phrase "fairly unique" but I don't think I've ever heard anyone say that. I'm not that fussed. I think something sure can be unique, but boringly so, like a unique sponge, whereas something that was spectacularly unique such as a spoon that could time travel or a quirky 80s song should be "very unique" and not just "unique".
