Get the cumgasm mug.
A half of a hand job. Usually happens when the girl realizes half way through that she doesn't want anything to do with your disgusting penis, so she goes home instead. Often the male at the wrong end of this technique will come up with excuses in order for his friends to not look down on him, such as "when you have a chick squeezing on your dick it's not pleasurable."
Poor Adam, only able to get a half job.
