repeated too often
overfamiliar through overuse "bromidic sermons" "his remarks were trite and commonplace" "hackneyed phrases" "a stock answer" "repeating threadbare jokes" "parroting some timeworn axiom" "the trite metaphor `hard as nails'" - old hat- well worn
not challenging
dull and lacking excitement "an unglamorous job greasing engines" - unglamourous
completely ordinary and unremarkable "air travel has now become commonplace" "commonplace everyday activities"
