I have come upon the sentence with the word that I cannot get in Crash Course Anatomy & Physiology. It is at around 46 seconds. Here is the context:

Astronauts often experience things like trouble sleeping, puffy faces, and loss of muscle mass, but perhaps the most serious damage a microgravity environment causes is to the bones. And bones, well, they're pretty clutch.

I have looked up the meanings of the adjective clutch in a bunch of dictionaries, but none seems to fit.

    I would love the know the next sentence (but would rather not have to watch the video).

It's an odd usage in my opinion. From M-W

Definition of clutch for English Language Learners
: happening during a very important or critical time especially in a sports competition
: able to perform well in a very important or critical situation especially in a sports competition

In this case, he's trying to be funny. You can tell by his delivery. The usage of the word is suggesting that bones are handy, or useful, in a critical situation. But that's misleading. The bones themselves are critical. Without bones, you wouldn't be able to live.

  • That is strange to me. I looked up the word in Urban Dictionary and got kind of the same meanings.
