I often address people of all genders as "dude" but a female coworker said that dude has origins only pertaining to males and is therefore itself male. She challenged me to find a word to address all genders that has feminine origins. Any ideas?

Edit: I'm not necessarily looking for a feminine alternative, nor am I trying to convince my coworker that dude can be male or female. Her larger point was that dude was originally masculine and is used for all genders (same goes for buddy, et all). She didn't think there were any terms with female origins that are now used for both male and female. That's what I'm looking for.
