have nothing on someone or something

have nothing on (someone or something)

1. To have no discernible advantage over someone or something else; to not be any better than someone or something. Yeah, you're pretty good at basketball, but you have nothing on my older brother Steve. Video game systems have gotten pretty impressive in recent years, but in my opinion they have nothing on the classic systems from the '90s.
2. To have no decisive incriminating evidence against someone; to have no proof of wrongdoing or criminality about someone. The police can insinuate all they want, but they know they have nothing on me that'll stick.
3. To have no information available about someone or something. I got this history book for my report, but it has nothing on the topic I want to write about! The library is horribly outdated—it has nothing on the current president!
