Imagine a volcano in your kitchen, but instead of lava, it spews out these noxious gases that could make your cat vomit and you second-guess your last pizza topping choice.
Here's a edgy example sentence: "The new gas stove 'applies fumes' to my living room, turning my favorite couch into a sticky, toxic sausage."
