Picaflor literally means "hummingbird." However, in many Spanish-speaking cultures, it's also a colloquial term for a "womanizer" or a "player" – someone who flits from one romantic interest to another, much like a hummingbird sips nectar from many flowers.
In "Siete Tragos," the lyric "en el sexto trago empiezo el picaflor" suggests that after several drinks, the singer starts to embody this persona, perhaps seeking out new romantic encounters to forget a past love. This double meaning makes it a very interesting and culturally rich word.
Have you ever tried to drink away your problems? La Zenda Norteña's "Siete Tragos" [Seven Drinks] is all about that feeling. Our singer is clearly heartbroken, admitting, "yo solo me gustabas junto a mí dejaste un dolor profundo y hace un tiempo nada me hace feliz" [you alone I liked, next to me you left a deep pain and for a while nothing makes me happy]. He's trying to forget his ex with "otros labios, otros aires, pero nada se compara a ti" [other lips, other vibes, but nothing compares to you].
He goes through the stages of getting over someone, one drink at a time. The first drink brings back memories of kisses, and by the second, the sadness hits because he knows his ex is better off without him. By the third, he's ready to call her, but his body just can't handle it anymore. It's a pretty relatable, if a little messy, journey through heartbreak and trying to numb the pain.
