Picaflor literally translates to "hummingbird" but it's also a common slang term in many Spanish-speaking countries for a "womanizer" or "playboy".
In this song, Kenia OS sings, "Ya no caigo con cualquier picaflor" (I no longer fall for just any womanizer). She uses this clever double meaning to assert her independence and show that she's too smart to be fooled by charming but insincere men.
Kenia OS is here to tell you that she's not impressed by your fancy things! In "Dinero," she makes it super clear that she's over all the lies and doesn't want anyone's money. She sings, "Yo no quiero tu dinero, Mentirosos ya no quiero" [I don't want your money, I don't want liars anymore].
She's a confident woman who knows her worth, telling potential suitors, "Una chica como yo no consigues donde sea" [You don't find a girl like me just anywhere]. She's got her own style, with "En el cuello tengo hielo, hielo" [On my neck I have ice, ice] and "Otros miles en el suelo, suelo" [Other thousands on the floor, floor]. She's not falling for any more sweet talk or "galán de telenovela" [telenovela heartthrob] acts. Kenia OS is basically saying, she's moved on, changed the locks, and is doing just fine without anyone's fake charm or cash!
