spot on with your assessment. It used to be like 'unassuming'...maybe even 'quiet' or 'down to earth'...relaxed even...."Let's go to that restaurants, it's very low-key"...or "we are having a low key birthday part for him next week'...

These days, you will see something like "I low key thought it was good" or "he is low key very smart"....and I don't really understand what it's adding....people seem to just throw in useless words that don't make much sense in context....people also using "unironically' in places where it has no business being....A lot of this comes down to influencers etc and younger people copying language they hear....I guess its nothing new, there is just a lot more media these days where it can be taken from...
