You insult or diss someone and at the same time you big them up. Usally complimenting someone followed by a negative remark. Or bigging someone up and dissing them in the same breathe, leaving them with mixed emotions.

Bystander: You guys are good at diss ups... To bad you're both shit at counter-strike
