Cuajado literally means "curdled" or "set," like cheese or gelatin. However, in Mexican slang, it takes on a completely different meaning and is used to describe someone who is very muscular, rich, or well-established.
In the song, the line "este cholo está pero bien cuajado" means "this guy is really well-built/loaded." It's a fantastic example of how a common word can become colorful slang, painting a vivid picture of a person's status or physique.
Fuerza Regida's "GodFather" drops you right into the middle of a wild, non-stop party. The song is a boast about living a life of excess with no apologies. The narrator is surrounded by cash, friends, and women, claiming, "Un chingo de paca', un chingo de dinero / Y andamos como queremos" (A ton of cash, a ton of money / And we do whatever we want). This isn't just about wealth; it's about the freedom that comes with it. He's partying for three days straight with his friends and describes a scene filled with drugs, from weed to cocaine, and drinking whisky.
What makes the song interesting is how it mixes this gritty party lifestyle with high fashion and a sharp sense of humor. The same guy who has a "bien filosa la navaja" (very sharp knife) is also "Bien guapo de Dolce Gabbana" (Looking handsome in Dolce & Gabbana). He even includes a funny little scene where someone's mom calls him a "pinche tecato" (fucking junkie), and the reply is, "Mami, este cholo está pero bien cuajado" (Mom, this cholo is really loaded with money). It's a blunt and confident track about living a dangerous, luxurious, and completely unrestrained life.
