What's in a name?

Today something happened that got me to thinking. I was on facebook and I heard that "infamous" pop... I got a random message from a friend. He said "JAMMMMMYYYY" I paused and looked at it with my head cocked to the side thinking "why did this dude just call me Jammy?" and I was initially angry about it. I was frustrated by this because that is what my mom has been calling me since I was a little kid. One of her many nick names to be honest haha. But anyway, I was frustrated because I associated that name with women in my family (since they call me that). I then put up a tweet about the instance, and a couple people said they were going to start calling me that. I was a little upset, but then I sat and thought about it. It really shouldn't matter who calls me that, dude , lady. The stipulation I had put on the name was kind of stupid. It depends on who you are, and how close I am with you. THAT is what determines. So for some of you reading this, feel free to call me that. Do you have weird stipulations for nick names of yours?
