Hé, I'm a bit embarrassed for my ignorance right now.
But slangs are always confusing before some get to the mainstream language!
I mean, I had to google "chingale", and that took me to something misleading of the urban dictionary.
Try it yourself, if you will.
Whatever. Now I want to say we still have so many sangliers over the country for real, that it still finds excuse for their barbarous seasonal hunting parties. Like "chasse à courre" involving large packs of dogs, horses and all the laughable costumes, that's of course a traditional symbol from the past.
In other words, nobles invited by the bigger nobles to butcher animals...
Chingales would proliferate, multiply like rats over the country.
I'm only from Paris, not from the countryside. So I don't know how they still manage to multiply like that, as the country was sevely deforested for real. This is not just an Astérix comics joke. It is scientific conclusions, and JManc is right in saying so.
I'm against that kind of hunting customs. It pisses me off whenever I have to kill a spider in my home, and I'm even trying hard to become a vegan to decrease violence within myself.
That's partly why I want bigger monsters like bears and dinosaurs back in the country, so people don't have to kill "chingales" like they would kill rats.
Bugs are always killed by bigger bugs.
Besides, I'm not scared of dinosaurs. But I'm scared of men like you.
You're far more dangerous.
