Its a term used for lizards like hybernation for the winter , if you brumate them, (keep them at cooler temps for the winter months) instead of their normal hot temps, they tend to sleep, their metabolism slows and they usually dont need to eat, they do need to be hydrated given water weekly, it helps them in the spring to be able to breed, like a rest period, also a rest for the owner as far as the cricket bills hehehehe, you can look it up to get a better more detailed answer for the proper temps when doing this and so on, but I just wanted to tell you what it was. And no it is not a dumb question, we all had those same questions when we were new here, and we sometimes have ridiculous, (dumb questions as you put it) now too
so always ask, somebody here can answer, except for John Eddington hes a goofball , kidding John, LOL if ya don't know what that means its laughing out loud ,we do that all the time around here,
