Now is the time of the Words of the Year… lists. You should have a look at the LinguaBishes list (and the rest of their site). They include words and phrases that people have been using (mostly online?) and (re)defining to express things that everyone is feeling at some point. I like their list the best.
And, not for nuthin, but the American Dialect Society’s Slang/Informal Word of the Year looks a lot like the LinguaBishes list.
I love the top definition of yeet on the Urban Dictionary, especially the third example. Yeet!
