Someone who is stupid or says something stupid or someone who deserves to be jerk fingered.
Gerard: Can you eats Lions
Tim: You fucking Jerk Finger

And when you call someone a jerk finger, you jerk off your left index finger then point at the person in question with the right index finger and call them a "Jerk Finger". I'ts all in the fingers.
