Chambear is a very common slang term in Mexico and other Latin American countries for "to work" or "to hustle." It's a more informal and colloquial alternative to the standard verb trabajar.
In this song, Larry Hernández uses it in a confrontational way, telling his detractors to "Pónganse a chambear" (Get to work) instead of gossiping. It's an interesting word because it reveals a more casual, everyday Spanish that learners might not find in textbooks, and it perfectly captures the song's defiant tone.
Get ready for a bold and unapologetic anthem! In "Las 745," Larry Hernández and Los Dareyes De La Sierra deliver a powerful message to all the haters and gossips. The title itself comes from a key line where the singer declares that other people's dislike for him is just one of 745 things he couldn't care less about. It's a song filled with bravado, telling critics to stop talking and "get to work" (pónganse a chambear).
The artists paint a picture of someone completely unfazed by negativity. While others are busy with rumors, he's relaxing with a cigarette and a glass of expensive whisky, promising that his success will only grow bigger in the coming year. The lyrics are direct and confrontational, using colorful slang to tell the "big mouths" (hocicones) to get out of the way, because he's feeling fierce (ando fiera) and won't be stopped by anyone.
