Tim Sendra of Allmusic gave the album three out of five stars review, and said the album had the "cheesy drum machines, samples, and off-kilter lyric approach that make " Jerk " so good", "the duo stick to the template [of "Jerk"], considering the uniqueness of the sound they've created and also the fact that it's a debut record made by teenagers, and an impressive and unfailingly fun debut at that." The review goes on to point out that "the reliance on the "Jerk" sound can be a little monotonous, there are enough variations along the way to keep things interesting." He also says "The duo's flow is not incredible but they spit convincingly. If you were looking for undisputedly pop-rap with a fresh sound and a light lyrical touch, the New Boyz debut is a fine destination."  XXL said that the album delivered "unexpected lyrical talent" but that it lacked "sonic variety". The review also goes on to say that the album "is no hip-hop classic, but rather the breath of fresh air rap needs."  Jeff Weiss of The Los Angeles Times gave the album three stars, commenting that the album "is a catchy and charismatic debut that should engender pleasant teen nostalgia in anyone old enough to vote and help explain why for the last six months, the kids have been saying out with the old, in with the New Boyz.".  The review also said that the album "successfully strikes a balance between introducing a new sound (the minimalist bass-heavy bounce of jerk music) and style (skinny jeans, Vans and "colors that ain’t even on the rainbow"), with traditional teenage themes (girls, the desire for self-expression, adults who don’t understand, girls). The result is a West Coast antidote to the South’s veritable monopoly on homeroom rap—a relentlessly breezy and fun ride through the lives of a pair of class clowns bent on enjoying the face cards that fate dealt."  The Selby Times said that the album "is about as happening as it gets for teenage music with an attitude, even if it makes adults' eyes roll in disgust."  Wendy Roby of BBC said that, "But overall their sheer chutzpah wins you over – and with its day-glo tongue wedged so very firmly in its cheek, Skinny Jeanz and a Mic is hard to resist."  Jon Caramanica of The New York Times called the album "one of the year’s most charming rap debuts, and certainly the least expected."  In a separate review, he named the album the sixth best album of the year, commenting, "Emerging from Southern California’s jerk scene, this teenage duo made an album that’s appealingly young, simultaneously wide-eyed and knowingly lewd."  's Nathan Slavik was less positive, predicting that the album would be "the last time we hear from the New Boyz."
