A person that feels a sense of
pleasure, either sexual or
non-sexual, by causing either physical or emotional
pain to others.
Personally, I do it cause I can and I like it.
Emotional-
Person
1- Look, my new hamster.
Sadist- Mate, that's not a hamster, it's a piece of flufffy poo.
I can't believe you wasted good money on that piece of
crap.
Person
1- You're such a sadistic prick.
Physical-
Person
1- Aah man, My arm seriously hurts.
Sadist- Really?
Person
1- Yeah, I just smashed it off of the door frame.
Sadist- So does it hurt if I do this? *hits his arm*
Person
1- Ow, yes it does.
Sadist- Yeah I thought it would.
Person
1- You sadistic bastard.
