Jack Flack

The father figure who appears from the mist to save the lost. Jack Flack is a legend who wears a black leather sport coat, appears from nowhere and vanishes once he has restored confidence to the scared and doubtful hero. He is a modern day saint.

(from the movie Cloak and Dagger) In a mist of confusion the boy ran headlong into the ghost-like Jack Flack.

Jackblackish

When a good movie which has a cast containing Jack Black involves him too much in the movie, subsequently ruining it.

''King Kong was pretty good yeh. Watts and Brody did their part, but to be honest it was a bit Jackblackish sometimes''
