Falsehoods, nonsense, or foolishness. Baloney in this sense might have originated from the word "blarney," which means flattering or nonsensical talk; more usually it refers to bologna sausage, which is blended from different meats, therefore implying content of inferior or dubious quality. Primarily heard in US. You're going to give me $5,000 if I sign the lease today? What a bunch of baloney.
