When a beverage company salesman has the easiest job but bitches and moans about it to the hardworking merchandisers. They have not just a cake job but a cupcake job.
The tired merchandiser had a blank stare listening to the salesman complain about his cupcake job.
A pose in which one uses the top side one or both hands to frame their chin. Searching google images for "cupcake pose" will come up with examples done by One Direction.
