Extrovertido is a perfect cognate, meaning it looks and sounds very similar to its English counterpart: 'extrovert'. It's an easy and useful word for English speakers to add to their vocabulary!
In the song, the singer playfully describes himself as "un loco extrovertido" (a crazy extrovert) to whom his love interest has given meaning. Using a personality trait like this, instead of more traditional romantic language, makes the song feel modern, personal, and endearing.
If you have ever had a few drinks and suddenly felt bold enough to confess all your feelings, Grupo Marca Registrada wrote this anthem for you. The Mexican group lays it all on the line with zero filter, mixing sweet romance with a tipsy party mood. The narrator admits right away: "Me da vueltas la cabeza, tomé bastante cerveza" ("My head is spinning, I drank a lot of beer"). He calls himself an "este loco extrovertido" ("this outgoing crazy guy") who found purpose the moment his crush gave him attention, and now he is dead set on making her his "princesa" ("princess").
There is no subtle flirting here; the lyrics are as direct and playful as it gets. He piles on affection with "Te quiero, me gustas, te adoro, preciosa" ("I love you, I like you, I adore you, gorgeous"), swearing that he cannot focus on anything else. He even jokes about his drinks helping his romantic mission, declaring "Mi botella de tequila quiere besar tu boquita" ("My tequila bottle wants to kiss your little mouth"). It is a fun, lighthearted love confession where having someone sit right beside you completely turns your day around.
