What is Flinned?
1.
The act of being screwed over, fucked over, or hung out to dry by a person previously deemed as a friend. This act is particuarly painful because the person committing it was thought to be your friend.
"Dude we got totally flinned when he left us at the concert without a ride home."
"That motherfucker has flinned me for the last time!"
