Orbit gum commercial - Chinese obscenity

[jsc1953]

A new commercial for Orbit gum (with the perky blonde): two Asian women engaged in a kick-boxing match. One discovers she's broken a nail, and exclaims something loudly in (possibly) Chinese. A shocked silence descends on the stadium; a mother covers her child's ears. Tag line: "dirty mouth? clean it with Orbit gum".

Any chinese-speakers know what was said?

"You killed my brother! Now you must pay!"

I believe it is "jian huo," meaning tramp/slut.
