I like bbq's too! wish my weekend contained bbq's...

anyway...
Props is just a word. What matters is the connection the word implies... Within poser, anything non-figure is a prop, an extra an additive on the side.
Its status is not defined from an artworks point of view. You can make anything a topic, point of interest, additive, or even plain scene-filling material, theres no way of setting up a rule for this.
So instead objects are named from the applications perspective. Poser makes figures, so within the program, anything that isnt a figure is a prop, simply because it doesnt match up with posers core functionality.
