(Mexico) (Vulgar) Fucking loads of (a large amount of), fucking too much (excessively).
Derives from "chingo" (large amount) and "madre" (mother). Madre, as a Mexican offensive placeholder, is appended to the already vulgar "chingo" to add strength to the statement.
A chingamader is a word that has been made up or transformed from a spanish word meaning, "stuff" or "things". Now it's just an insult. Or a derogatory way to explain body parts.
"You are a fucking chingamader!" or "Where you been hiding those lil chingamaders?"
