A loving friendly person. Someone that goes out of there way for others. They are the funny one of the group. They normally don't want to blend in, they want to stick out from the crowd!
A sadist is one who enjoys inflicting pain on OTHERS. The description given by the other poster describes a masochist (someone who enjoys being inflicted with pain). I'd also like to point out that "sadic" is another way of saying "sadistic", not "sadist".
Pyramidhead is a sadic monster who attacks those who feel guilt or desire punishment (also known as a masochist).
