make the sparks fly
Start a fight or argument, as in If Mary finds out he went to the races without her, that will make the sparks fly. In this idiom, the small particles of a fire called sparks are transferred to an inflammatory situation. [Early 1900s]
Do You Remember This Fly 90s Slang?The 90s might be in the past, but that doesn’t mean the language from that decade needs to be. Sure, there are some words we don’t need to hang onto (boo-yah! and not! come to mind), but there are a few we’d like to keep around. So, try out these words from the 90s for those days when you’re feeling especially fly.
