“Bologna” is the name of a city in Italy, pronounced “boh-LOAN-ya.” But although the sausage named after the city in English is spelled the same, it is prononced “buh-LOAN-ee” and is often spelled “baloney.” Either spelling is acceptable for the sliced meat product.
Then there is the expression “a bunch of baloney.” “Baloney” in this case probably originated as a euphemism for “BS.” When it means “nonsense,” the standard spelling is “baloney.” People who write “bunch of bologna” are making a pun or are just being pretentious.
