Descoloca literally means "to displace" or "to disorient." It's an interesting word because it describes a state of being thrown off balance, both physically and mentally.
In the song, it's used to describe how a few drinks can make someone lose their composure: "Copas en la cuarta ya se descoloca" (After four drinks, she's already disoriented). This word captures the playful and slightly wild atmosphere of the song, making it memorable and engaging.
Get ready for a party anthem! "Copas" is all about a night of letting loose and losing control. The song describes a woman who, after a few drinks—"una, dos, tres copas" (one, two, three drinks)—completely transforms. She's described as classy and beautiful, but she doesn't fall in love and dances by herself, completely unrestrained.
The singers are captivated by her dual nature. She might seem innocent, but they see a mischievous side hidden "detrás de su sonrisa" (behind her smile). They notice she's been hurt in the past and is on the defensive, but they want to show her a good time with no strings attached, suggesting a romantic escape "en la orilla de la playa" (on the shore of the beach). It's a song celebrating a wild, carefree night where inhibitions are left behind.
