Sassive-Aggressive

To be passive-aggressive in a sassy tone of voice. The passive-aggressive comes from the words you use, while the sass comes from the vocal inflections you use when talking. It is more effective than just being sassy or passive-aggressive because you can use both at once for a double-whammy of insults.

Girl 1: Damn bitch, that was really sassive-aggressive!
