It’s mind bending and somewhat creative trying to picture these expressions:
~Elmer’s scowl was coldly demented.
~Nina wore a lacy smile.
~Old Beanwhooper sat with one leg ajar and the other removed at a distance.
~Uncle Raemon was the first to let out with a barn melting zinger.
~My boss is always so ultra banjo-man.
Now that I’ve indulged myself, perhaps you can find a way to fit one or two of these into a scene. Feel free to find your own descriptions that challenge us to peel through our own mental images.
