Labia literally means "lips" in Spanish, but in this context, it's used as slang for "smooth talk" or "the gift of gab". It refers to someone's ability to persuade or charm others with their words.
In the song, the line "Tirando labia, que yo voy pa'lante" suggests that despite someone trying to charm or talk their way into something, the singer is determined to move forward. It's an interesting word because it highlights a common Spanish slang term that adds a layer of street smarts to the lyrics.
Rels B's "TU VAS SIN (fav)" is a super fun and confident track all about chasing someone you're really into! He's not shy about his feelings, singing "Yo la querÃa pa' mÃ, mi bebeci-, bebeci-" [I wanted her for me, my baby, baby]. He's clearly smitten, describing her as if "Una varita diseñó su cuerpo" [A magic wand designed her body] and saying "si está más buena, explota" [if she were any hotter, she'd explode] – a pretty bold compliment!
It feels like a flirty dance, with him wanting her to "baile, me baile" [dance, dance for me]. He loves it when she sends him hearts, admitting "Llevo tiempo detrás de ti" [I've been after you for a while]. He's ready for everyone to know they're together, saying "En la calle todos saben quiénes somos" [Everyone in the street knows who we are] because they "brillamos como bli-bling" [shine like bling-bling]. It's a playful, direct, and totally catchy song about wanting someone all to yourself.
