Word of Mouth: Culacino
Culacino [kuhl a CHEEN o] n. Italian for the mark left on a table by a wet glass.
Leave it to the Italians to come up with such a pointed word for such a precise thing! Remember it next time you set a cold glass down on a table without a coaster...
The pretty laser-cut wood coasters in the picture come in a set of eight for $40 at A+R.
