A shining material used for ornamental purposes; especially, a very thin, gauzelike cloth with much gold or silver woven into it; also, very thin metal overlaid with a thin coating of gold or silver, brass foil, or the like.
Something shining and gaudy; something superficially shining and showy, or having a false luster, and more gay than valuable.
Showy to excess; gaudy; specious; superficial.
To adorn with tinsel; to deck out with cheap but showy ornaments; to make gaudy.
Time, which runs through the world like an endless tinsel thread, seemed to pass through the centre of this room and through the centre of these people and suddenly to pause and petrify, stiff, still and glittering... and the objects in the room drew a little closer together. Robert Musil
