Chinqui can be used to describe almost anything. Whether you are complimenting someone, commenting on a certain situation, or setting. Its an adjective for everything. Chinqui can be a substitute for cool or can even be used when something is uncool.
Those boys are so chinqui (thats either describing them as attractive or unattractive, the meaning of Chinqui in context highly depends on the tone when said. That is the main point behind its reasoning and why it is so versatile.)
