I've eaten chapulines (grasshoppers). Their taste reminded me of what I think slightly toasted grass might taste like. I didn't care for them, but would try them again if someone who liked them recommended a different preparation and I wouldn't hesitate to eat them if I needed protein.
I find it weird that people do that with language. Did you also drink agua, breathe aire, walk on calles, or sleep on camas? Why is it we only do this for some things but not others?
Is because there is not an exact equivalent to the name 'chapulin' in english, and is a distinctive name, so is useful to keep the word.
