Despegar literally means "to unstick" or "to take off," like a plane from a runway. It's the opposite of pegar, which means "to stick" or "to glue."
In the song, Chayanne sings "y más nunca nos despegamos", meaning "and we never separated" or "we never came unstuck". It paints a sweet and vivid picture of a couple who became inseparable right after meeting, as if they were glued together. This memorable word choice perfectly captures the song's theme of an enduring, passionate connection.
Puerto Rican pop star Chayanne is head over heels in love here, and he is not trying to hide it. The song kicks off with him admitting he keeps his partner's photo in his wallet (Tengo en mi cartera tu fotografía [I have your photograph in my wallet]) and misses them whenever he travels. He describes their connection like a never-ending honeymoon where everyday life tastes better (todo me sabe mejor [everything tastes better to me with you]). Whether they are crying or laughing (Subimos, bajamos, lloramos, reímos [We go up, we go down, we cry, we laugh]), they stick together like a cup and its wine (Somos la copa y el vino [We are the cup and the wine]).
Things get fun on the dance floor when Chayanne compares their chemistry to a blazing bonfire, singing Quemamos la noche bailando bachata (We burn up the night dancing bachata). He even drops an affectionate nod to his own musical catalog, telling his partner to ask the DJ for Humanos a Marte (Dile al dj que toque Humanos a Marte [Tell the DJ to play 'Humanos a Marte']), which is his own hit pop track from 2014. Passersby might wonder what is wrong with him (La gente no entiende qué rayos me pasa [People don't understand what on earth is wrong with me]), but he is too busy dancing to care.
