I've been described as a "girl with a right blokey sense of humour". But I assure you, I have girl parts.
I like laughing. So if your good at making people laugh, I'll generally make you say said funny thing until it's no longer funny anymore. Until five years later, when you say it again, and so the cycle goes.
I also love impressions. If you can do Christopher Walken, you'll never get rid of me.
I know what you're asking yourself, and the answer is yes, I have a nickname for my penis. It's called the Octagon. But I also nicknamed my testes. My left one is James Westfall, and my right one is Dr. Kenneth Noisewater.
