1)Character from CW series Supernatural. The younger brother of Dean Winchester, Sam has only two expressions: 'smug smile' and 'intense stare into far distance.'

similar in type to Michael Scofield of Prison Break.

2) a self-absorbed hypocrite.

Teenaged girl: I love Supernatural, Sam Winchester is sooo HOT!!

Sensible person: Supernatural is cool but shut up.
