To be extremely tedious or dull. The literature abounds with epigrams concerning bores. Both of these clichés for being exceedingly boring allegedly date from the nineteenth century and are much duller than, for example, “Society is now one polished horde, formed of two mighty tribes, the Bores and Bored” (Byron, Don Juan), or “Bore, n. A person who talks when you wish him to listen” (Ambrose Bierce, The Devil’s Dictionary).
