Today, our team was bought a drink or two by our company, so I was talking with an Afroamerican colleague and was trying to describe him that I had seen San Francisco in San Andreas GTA game, but he couldn't understand about what version of the game I was talking about, so I was trying to describe him the main player, which is a black person.
In my attempt, I said black guy, but as soon as I started the phrase I decreased the volume of my voice and I actually told that only to the 3rd guy in our conversation and I do not know if the Afroamerican person really heard me or even if he reacted, because I looked intentionally the other guy, since I felt I was telling something bad.
Tonight, some people stole our phone, and they happened to be black, and when I finally found a police officer, I was trying to describe him the scene and in my rush I said "..the black guy grabbed the phone.." and the police officer was also black. So did I say something offensive? I only that afterwards...
So, is the phrase "black guy" accepted for a tourist like me (it's freaking obvious I am one)?
