 Lyrically, the song shows Rihanna sexually seducing her love interest, while revealing her "nasty secrets". According to Julianne Shepherd of Spin, Rihanna "coyly dares" 'her lover to "sex her up"'. In "Roc Me Out", Rihanna uses her "militaristic alternate persona" and interprets the lyrics "with a command and directness befitting" of it. Rihanna complains to her lover throughout the lines "You ’ re taking too long to get my head on the ground / And my feet in the clouds," before cooing, "I ’ ve been a bad girl, daddy". She gives him instructions while singing "Get my head in the ground and my feet in the clouds". Priya Elan of NME commented that the song sounds like a "‘ Rude Boy ’ re-tool from the vocal delivery to her 'Come on boy' line." In the end, Rihanna reveals the "dirtiest secret" through the line "I ’ ll let you in on a dirty little secret, I just want to be loved". David Amidon of PopMatters described the line as the song's "not exactly a dangerous sentiment".
