a) A mythical place which is very, very, very, I MEAN VERY far away... In Mexico, when someone sends you there, is indeed sending you a strong message to bugger off for good. If you don't take heed, most likely you'll be next fucking your mom (chingando a tu madre).
b) Mythical mom who delivered you though her asshole cuz her cunt was too busy fucking the niggers in the hood. In Mexico, if someone tells you that you are his son (eres un hijo de la chingada!) this person is saying you have the character defects that one would think would result from such a stressful birth.
a) Ya me tienes hasta la madre, vete mucho a la chingada, cabrón! (Yo got me up to my balls, go to fucking hell you shithead!)
b) Sabes, siempre has sido un hijo de la chingada... (you know, you have always been such a son of a bitch...)
