I've recently caught a very rare disease. It's a bizarre illness that causes me to turn female when somebody says a certain word. I don't mean to be disrespectful to the opposite gender, but I'm comfortable with my currant gender, so don't say the disease's trigger word. I won't say what the word is, but I'll give you some hints.
1) It appeared on the Australian 20 cent coin
2) It can be found in Australia
3) It can secrete milk
Please, please, please, PLEASE do not say the word that I'm hinting at.
