Hi, is there any equivalent expression? We sometimes say this when something is really great... I've found in the WR dictionary that bomba, besides the technical terms, can be referred to as "bombshell", but I'm not sure whether this is appropriate for the meaning I'm trying to express. An example: Imagine a new invention which is really innovative, and you say ¡"Guau, es la bomba"! Any suggestion? Thanks in advance.
