Critical reception
Writing for RapReviews, Damon Brown cited the song as one of the tracks from Me & My Brother in which the "guest stars fall in line right into Ying Yang's way of doing things, as opposed to bringing something fresh to the mix", which he described as interesting and somewhat disappointing. Gil Kaufman of Rolling Stone mentioned the song as an example of a track with "shouted, crack-pipe catchy hooks" and verses that "feel like poorly executed foreplay".
