'A flick' is when an amateur skateboarder attempts a
kickflip and instead 'flicks' the board out in front of him and possibly lands it one
footed, but lacking the correct technique to
land it properly.
A kickflick doesn't exist however 'a flicker' is a sick trick, usually a flip or other sweet move over a gap or off a launchramp.
"
The poser went of the launchee and did 'a flick'. His board
hit a girl in the head."
