Allmusic writer John Bush called the song "irresitible", selecting it as one of the best songs from Monster along with "Rap Is Dead" and "U Know I Love U". Writing for hip hop website RapReviews, writer Steve Juon complimented "A.D.I.D.A.S." and the way it addressed the sexual theme of its title, describing it as a "light-hearted song about getting a nut".Uncut magazine called the song's tempo "bouncing" and praised how the song displays Killer Mike's "playful pop sensibilities".
