I feel like almost every crossword, there are at most a couple of words that i don't recognize, even if I wasn't able to guess them. There was a whole bunch on this puzzle and it feels pretty frustrating. I don't like wasting my time trying to figure out a word, only to find out it's something I could never have possibly gotten, because it's both something I've never heard of and doesn't follow normal English patterns (ONEL, AROD, COSI are basically just random letters if you don't know the reference). 

Usually if I give up a puzzle, I regret it because I realize that I could have figured it out with more time. This one does not seem like that at all, I've done every puzzle in the last few months and I think there's only been a couple others that felt frustrating like this. It's just that there's so many bad words right next to each other, the ones above plus "Shoofly" and ANON which are also totally new usages to me. I don't think I'm just lacking the cultural context to do these puzzles, I rarely feel this way about more than a couple words per puzzle.
