A Lavalle
Laval is where the gangsters hang out, and if you don't know how to talk to them, you're gonna get roasted.
Laval is like the gangster version of a neighborhood, but with more slang and less sense.
If you go to Laval and don't speak Lavalois, you're gonna get called a dummy.
Laval has four languages, but they all basically just say 'you're an idiot' in different ways.
