Some of these aren't exactly 'new' words. Both in the sense that they've been around for quite a while, and also in the sense that they're just combining existing words that don't really have any special new meaning. For example 'doorbell camera' hardly even seems to merit an entry as a "new word". It's a pretty self-explanatory compound noun, not a new word. Likewise for 'air fryer', although perhaps it's not as self-explanatory. Even 'dad bod' is pretty intuitive if you think about it for a second.
I'm kind of curious on their standards for 'new'. Two of the food ones (horchata and chicaron) aren't new words, but rather just loan words. I've been hearing them since I was a kid, what with living in a predominately Hispanic region. Ditto for fluffernutter, :down: which has been around for about as long as the nasty marshmallow cream has been. Some of these words have been around for quite some number of years, while others (covid-related) do seem to be relatively knew.
I honestly thought 'amirite' was outdated internet slang at this point. I've been using it for many years, but hardly ever see it any more.
The only ones I wasn't familiar with were:
halotheraphy
otaku
fourth trimester
These two have new definitions or usages that I wasn't familiar with:
atroturf
breakthrough (in this specific, negative sense)
While I have heard of and knew what oobleck was, I still refer to it as 'silly putty'. Breakthrough has always had this notion of bypassing some kind of defensive barrier or hurdle, so again the only new aspect is that it can now takes on a negative connotation as well.
