"Carnalito" is like the cuter, more affectionate version of "carnal." In Mexico, "carnal" is a slang word for a really close friend—like a buddy or a bro. It comes from the word "carne," meaning "flesh," so it’s kinda like saying "brother from the same mother" or "family by choice."

When you add the "-ito" at the end, it just makes it sound even warmer and more loving—like calling someone "my little bro" or "my dude." It’s a term you use when you’re super tight with someone, like family. You'll mostly hear it among people when they’re hanging out, joking, or just showing love and loyalty to each other.
