have got nothing on (someone or something)

have got 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've got nothing on my older brother Steve. Video game systems have gotten pretty impressive in recent years, but in my opinion they've got 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've got 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's got nothing on the topic I want to write about! The library is horribly outdated—it's got nothing on the current president!
