Sleeper Dick 

A drawing of a penis in another persons school book that is drawn far through the book so that it is designed to be found and cause shock weeks or months after it is drawn, much like a sleeper agent.

Harry discovered the sleeper dick in his physics workbook, three months after we drew it.
