he term that northern Mexicans use to refer to anything narco
related. often used to describe a stereotype very common amongst drug cartels and dealers. chacalosos would dress in a mixture of ranchero
clothes (such as belts with big buckles and cowboy boots) and preppy guy clothes (such as polo shirts or brand jeans), it is also used to refer to a specific attitude these people show, usually cocky and feeling above the law. chacalosos aren't necessarily involved in drug dealing or trafficking themselves, but most of the time they are either blood related or have a close relationship with someone who does.
That guy looks very chacaloso with his huge truck and listening to that narco corrido
music. he must be the son of a drug trafficker.
