An acronym for "First Lady Is Really Gay" or "First Lady Is Really a Guy". (A reference to Hilary Clinton.)
Made famous by the 9/13/2008 opening skit of Saturday Night Live dialog:

Tina Fey as Sarah Palin: "Don't refer to me as a 'MILF.'"

Amy Poehler as Hillary Clinton: "And don't refer
to me as a 'FLIRG'. I Googled what it stands for and I do not like it."
