Hi Duke, thats Mexican not Spanish, I not shure what is hachero because in Spain we don´t use that word, but when he says hachero he is refering to someone in an offensive condition, and hijo de puta, you can imagine what it means...

I think this person didn´t have a good day!

But that text probably was in a dialog so it´s a bit hard to traslate without the rest, depends in the condition you say hijo de puta it could be an offensive or friendly.

If you need more help I will be glad to help you!
