Chingada is a very common, yet highly versatile and often vulgar, Mexican Spanish slang term. While it can literally refer to a sexual act, its meaning is highly dependent on context and can express a wide range of emotions, from anger and frustration to surprise or even admiration.
In this song, the phrase "hasta la chingada" is used to convey extreme exasperation and being fed up. The singer declares, "Ya estoy hasta la chingada," meaning he's completely had it and is utterly sick of the situation. This word is a powerful expression of his frustration and desire to end the relationship.
This song is a fantastic declaration of independence! La Septima Banda sings about someone who has finally had enough and is ready to move on. The singer has "Ya lo pensé mejor" [I've thought about it better] and decided they don't want anything from their partner anymore.
The lyrics are pretty blunt, saying "De mendigar tu amor y que me veas la cara / Ya estoy hasta la chingada" [Of begging for your love and you making a fool of me / I'm already fed up]. They'd rather be alone than constantly worrying because of their partner's reputation. The singer even offers to help with the bags, saying "Dime si te ayudo a acarrearte las maletas" [Tell me if I help you carry your suitcases] because their absence is exactly what's needed. It's a powerful and direct message about choosing peace over a toxic relationship.
