I did not see the price list. And I am referring to its usage in Colombia and my experience talking to guys in Bogota and in Medellin, or I would not have weighed in. In all cases, morbo was used to mean kinky, such as watersports. It would be strange indeed if it was commonly used both ways, but I guess not impossible. Thanks for providing a reference to evidence, as I agree with your interpretation of the price list--kink would indeed be expected to command a higher price.
Using Scruff to search locally in Bogota, I do find many guys who include morbo as a clear indicator of kink, including references to: bondage, watersports, domination and humiliation, blow-and-go, and even k9, complete with doggy emojis. But I also do find some that seem to be using it to mean affectionate. Confusing, and maybe can be chalked up to a high percentage of tourists/immigrants there, although one of the kinkiest guys identifies himself as native Bogotano. Maybe it's one of those things where you just have to pay attention to the context.
