Tits or no tits?

In an office with two males and two females would it be appropriate to yell out "Tits!" upon triumph or in excitement? I've used "Bad Ass" and "Killer," but have been apprehensive about the prospect of using such a sensitive term; I've also contemplated the use of "Jumanji," "Yanzee" and "YeYah".

Also, what other possible celebratory words or phrases should be used?
