Despite the the very specific directions you have been given, and despite the fact that the very extensive project is nearly completed, the client decides that it is flawed irreparably and you must pretty much start over. Oh, and it's not their fault that they gave you improper guidance from the get-go. You obviously are an untalented hack and incapable of reading minds. What kind of "creative" person can't read minds? Hack ...
The term comes from the "This is Spinal Tap" scene in which Angelica Huston presents an 18" Stonehenge monument to Ian because he wrote the directions on a cocktail napkin and wrote " for "inches" instead of ' for "feet".
"Why did you make that tag verbal and not sung?"
"You told us to do that in our meeting and you wrote it on this napkin that I'm holding right here. This one in my hand, the one that has your handwriting on it that says "make the tag verbal"
"Fuck the napkin"
