Obfuscate
You can lie and belittle right out (and perhaps reduce workplace tension) in the open and hurt nobody with a shared secret language. So, hearing (or saying), "We got a code brown on a Hasselhoff FLK and he's giving the O-sign," in a hospital corridor could be describing something hilarious, as long as you don't overhear doctors describing your condition.
** Don't share you secret language with anyone and Big Jo will never know what you're saying about her. **
