When
someone, usually named Norman,
who is typically a backstabbing
cocksucker, starts acting nice for no reason
tipping you off that he's up to something.
Jay: That damn Norman is up to something
Andrew: How's that?
Jay: Yesterday he was busy trying to fuck me in the
ass with the boss and today he's acting
like he's my
best friend!
Andrew: Whoa! Totally UnNorman! Watch your back bro!
