The term was coined at ad agencies to describe an art director that avoids involvement in a projects until it becomes a perceived problem at the production phase. Usually a result of forgetting the project was in the works. The art director will make a scene with their production team, order revisions (usually very minor taste fairy changes) and vanish as quickly as they appeared.
This type of art director is sometimes called a "seagull" for short.

The act of painting a Van Gogh style image with your dick on your partners back and ass after a thorough/ rough ass fucking. Using a nice mix of cum, lube, shit, and possibly blood.
