Morritas is a colloquial and somewhat informal term in Mexican Spanish for "girls" or "young women." It's a fun and youthful word that you might not find in a standard dictionary.
In the song, the artist sings about looking for "lindas morritas" (pretty girls), giving the lyrics a casual and relatable vibe. It's an interesting word because it reflects a specific regional slang, making it unique and memorable for learners.
Polo González's "Fin De Semana" is a fun look at how his life has changed, and how he's dealing with the haters. He starts by saying, "el fin de semana ya no he estado tomando buscar las lindas morritas me quitan las ganas para esto les chingo todas las semanas" [on the weekend I haven't been drinking, looking for pretty girls takes away my desire, for this I bust my ass all week]. He's working hard and focused, and he's not letting anything distract him from his goals.
He also talks about how people perceive him now that he's found success. He says, "soy muy sencillo ya te lo dije en el otro corrido mil cosas cambian no estoy precavido por eso piensan que soy presumido" [I'm very simple, I already told you in the other corrido, a thousand things change, I'm not cautious, that's why they think I'm conceited]. He's not trying to show off, but he's proud of what he's achieved. He even addresses the envy he's encountered, saying, "cayó la envidia era de esperarse pues cambia en mi suerte lo hice ver muy fácil pero pariente si fuera fácil por los fueran 20" [envy fell, it was to be expected, because my luck changed, I made it look very easy, but buddy, if it were easy, there would be 20 of them]. He knows his success might look easy, but he worked hard for it. He's not going to let the haters get to him, saying, "cuántas palabras yo no me espanto sólo hacemos que ella sigan hablando porque me motivan a callar bocas" [how many words don't scare me, we just make them keep talking because they motivate me to shut mouths]. It's a great song about staying true to yourself and enjoying the ride!
