The word lizard
"If I even think about having a cigarette or dropping an f-bomb, her head splits open and this nasty humpbacked lizard wearing an apron pops out. See, there it is."
It's a sentence from a book I'm reading now.
I'm interested whether the word lizard has any other meanings apart from that of an animal.
Well, I have this feeling because of the phrase "See, there it is" which means that the speaker either wants to have a cigarette or is about to say (or said) a swear word.
So what do you think?
Maybe I'm just overthinking this XD
