Desacatado literally translates to "disobedient" or "disrespectful," but in a more colloquial sense, especially in urban music, it means "out of control" or "wild."
In this song, the artist uses it to describe a woman who is acting freely and perhaps recklessly after being hurt in a previous relationship. He sings, "Dice que me quiere, pero se ha desacatado" (She says she loves me, but she's gone wild), implying she's not ready for a serious commitment and is living life on her own terms, which makes her intriguing.
"Siberia" is about loving someone whose feelings run hot and cold. The singer compares her to Siberia itself: warm one moment, freezing the next, never quite letting him fully in even as he falls harder.
Despite the mixed signals, he's all in. He pictures the simple, everyday parts of being together: smoking, watching Netflix, taking selfies, just being close. He calls her his lucky charm and says he wants forever with her, even talk of marriage.
The chorus keeps circling back to the same tension: she says she loves him, but she's been careless with that love, and every time the party starts up again, so does the cycle. It's a song about wanting someone completely while knowing exactly how uncertain that someone is.
