The term 'OLD-TIMEY OATH' can be broken down into two crossword solutions, EGAD and NERTS. EGAD is an interjection used to express surprise or dismay, and is derived from the Hebrew phrase 'hagadah, ' meaning 'tell me more.' NERTS is an acronym for 'Not Even Remotely True Statements, ' which is used to describe statements that are completely false. Together, these two words form an old-fashioned oath, expressing surprise and disbelief at something that is not true.
