what is legally considered slander?

This answer does not create an attorney/client relationship.  I am a S.C. attorney and board certified internist.  Libel is a written defamatory remark.  Slander is an oral defamatory remark.  In both cases you must prove you suffered damages due to the defamatory comment unless it falls into one of the following categories, which are so heinous that no damages need to be proven: (1) accusing someone of being unchaste; (2) accusing someone of having a loathsome disease; (3) accusing someone of being incompetent in his or her chosen profession and (4) accusing someone of committing a crime.  The truth is the one defence.  Furthermore, if one is a public figure, you must prove intent; unlike a private person where falsity is all that needs to be proven.
