But what is a SMILF, and why is that the title of Showtime's new dramedy, premiering Nov. 5? Contrary to what some might think, the S and M don't stand for soccer mom. In the case of the show, SMILF is an acronym for Single Mom I'd Like to F*ck. The eye-catching title is an appropriate one for the show, which follows South Boston native and single mother Bridgette Bird (Frankie Shaw) as she struggles to provide for her son, co-parent with her ex, and get back on the dating scene.
