Typically someone who is pale and sickly looking. This person will almost always bring down the vibe of a room because of his sickly appearance that can be misunderstood as having AIDs. Will usually try to fit into a crowd but will most likely be an outcast because of his AIDs appearance.
Derek asked me to go to lunch today but I passed because he just looks so sickly. What an AIDs boy.
Did you meet that kid who mopes around with no care in the world? Oh, you mean AIDs boy? No, that kid Derek hangs out with. I bet he infected him.
