Jose is right. In Argentina, “macho morboso” is slang for macho into kinky sex, willing to try and explore unusual, transgressive sexual desires. Sometimes they just mean “very sexual macho” or even “addicted to sex” in my experience. You see “macho morboso” a lot in escort ads in Argentina, also on dating apps as a way to brag about their sexual prowess and/or promiscuity. I guess Angel just went for a literal but naive translation, turning “macho morboso” into “macho and morbid.” That also explains why he followed it up with “I love sex “ which is most likely what he means by “morbid “ 😁
“Morbo” is also used to say you find someone sexy, very attractive/hot, or that the person has strong sex appeal, especially in Spain. For example,“Ese macho me da morbo” means “that stud turns me on.”
