(aloof, craven, glower, & worm), someone who takes pride in or
feels justified by scowling at someone else anonymously; expressing hostility towards someone, without verbally addressing that individual directly, privately or publicly; someone who conveys
anger with another individual, without saying
anything.
That
guy scowling in the restaurant
may be esteemed in his own community, but I now realize that he is either another glowerworm or just a figment of my twisted
imagination.
