心血来潮 is a four-character idiom (成语) meaning to suddenly get an idea or impulse out of nowhere — like a wave of emotion or inspiration hitting you. The literal image is 'heart blood comes like a tide.' You use it when someone does something on a whim, without planning or deep reason. It's often followed by 就 + verb to show the impulsive action.
