To "switch up" something means to change it or do something differently! So, to "switch up something a little bit" means to change it slightly. Ex: Let's switch it up and get take-out tonight instead of cooking. Ex: We decided to switch it up and go to the city this weekend. Ex: I'm going to switch up the music to something more lively. Ex: If you switch up a few ingredients, then the recipe is even better.
