Not that we need to open this can of worms here, but it's a pet peeve of mine that "vanilla" has become a term used to mean plain, boring, sheltered, standard, mediocre, underwhelming, basic, and uninteresting.

Vanilla is an amazing flavor that comes from orchids that must be hand pollinated to cultivate at scale, and has a long and interesting history. It's the second most valuable spice after saffron.

Just feels wrong to use that as a synonym for bland and blah.
