A review process whereby the proofreader believes a particular piece of work product is so terrible that it would be an improvement to:
1) Print out document/presentation
2) Pull down trousers
3) Squat over said document/presentation
4) Proceed to excrete on document
5) Return to author covered in human excrement
That PowerPoint Presentation was so horrible that I printed it out and gave it a Brown Spit-Shine.
Upon reviewing the first draft of Jim's presentation, I had no choice but to Brown Spit-Shine it. Jim's on holiday so his desk is going to smell upon his return.
I know the first iteration wasn't my best work by it didn't deserve to be literally shat upon with a Brown Spit-Shine.
