Well, I had a question on a reptile term I've been seeing a lot recently and this looked like maybe the best place to put it. What is meant by the word "dinker?" Been seeing it a lot with BPs and even some gecko/lizard species. I kind of have a vague idea of what it must mean from the context of where I've seen it used but I'd like a fuller explanation and to be sure my limited understanding is correct.
