 The uptempo song contains musical elements of salsa, cumbia, and reggaeton. Allan Raible from Yahoo! further found "flamenco-esque propulsion and modern electro and EDM touches". Marcus Floyd of the website Renowned For Sound felt that the song was reminiscent of the "Latino party vibe" characteristic of Martin's other songs. Other critics further found influences of African and Latin music in its instrumentation and rhythms. "La Mordidita" contains a soccer chant during its bridge. Rapper Yotuel has a short rap contribution in the song. Lyrically, "La Mordidita" which translates to "The Nibble" in English, talks about the lust felt for a desired person.
