Well bellaco mean horny. So bellequeria pretty much means filling realy horny. I'm Puerto Rican so we use it for a lot of different things. If we say (deja la bellaqueria). means stop f****** around. if we say (eso está bellaco.) mean that is nice,look good, looks phat. is the word we use very often. but it is a bad word so be careful how you use it & where to just it. hopefully this will help you out.
