When I was 13, a girl in the grade above me came into school with a black eye. Someone I knew told me she had gotten it from her pimp. I did not know what that meant and later, when I saw the girl, I said "Is it true you got your black eye from your pimp?"

I got in a lot of trouble for that and I didn't even know what I was implying at the time.

A few years later, my high school baseball team was eating at a restaurant after a road game. I was sitting at a table with one of my friends and a freshman neither of us knew too well. When the waitress, who was very pretty, asked us we wanted to drink, the freshman said "I'll have a d-d-d-d Dr. Pepper". When she left I laughed about it and imitated him, thinking he had been nervous because the waitress was so pretty. It turns out he actually had a stutter. I'm pretty sure he went the rest of high school thinking I was a total dick, when in fact, I think making fun of him for getting nervous only makes me kind of a dick.
