The Second Lady of the United States (SLOTUS) is an informal title for the wife of the Vice President of the United States, coined in contrast to the First Lady (who is almost always the wife of the president). The term "Second Lady" may have been first used by Jennie Tuttle Hobart to refer to herself, later fell out of favor, but was revived in the 1980s. During the 1990s the title was again abandoned, in favor of "wife of the Vice-President", but was later resurrected during the administration of Barack Obama.
