A childhood belief about places

I, like other posters, thought that when people said miami they were saying My ammy! But, I thought only men said it because I only heard sportscasters and weathermen say it, and they are both men on the station that I would watch! I thought that an ammy was a wife, like for example "My ammy is going to lose in the game against Tampa Bay today!" and "My ammy is going to get wet today, lots of rain!" I thought it was like a little form of banter.
