Placosa is a slang term, particularly used in Mexico, to describe someone who looks tough, intimidating, or gangster-like, often associated with a certain street style or attitude.
In the song, Lefty Sm sings, "Toda mi banda se ve bien placosa" (All my crew looks really tough/gangster-like). It's an interesting word because it's not standard Spanish and gives insight into the street culture and identity portrayed in the lyrics, making it memorable and unique to this type of music.
Lefty Sm's "Original" is all about staying true to yourself and your roots, no matter what. He kicks things off by saying he's "Original como Juan traigo prendido mi ghetto" [Original like Juan, I keep my ghetto lit], which tells you right away he's proud of where he comes from and isn't changing for anyone. It's a song about hustling, staying sharp, and having a tight crew.
He talks about the struggles, how they've been "viviendo en aprietos" [living in tight spots] for a long time, but that doesn't stop him from dreaming. Lefty Sm emphasizes that he's always on guard, with his "bola cuidando por donde paso" [crew watching where I go], and that he's got a lot of business, with "bastante jale mucho cliente tenemos en la fila" [a lot of work, many clients in line]. He's got that "puro veneno del bueno" [pure good venom] – a unique style and energy that makes his music hit hard. It's clear he values loyalty over quantity when he says, "Pocos amigos pero reales pa' que quiero veinte" [Few but real friends, why would I want twenty?]. He's focused on making money, not chasing fame, and he's not afraid to be blunt and direct. This song is a declaration of his identity and his crew's strength.
