IBS

Incredible Book Syndrome. A condition requiring frequent and prolonged trips to the bathroom in an attempt to finish a book with minimum interruptions from friends or family members.

I wanted to finish up Assassin's Quest the other night, but my wife wanted to watch Dancing with the Stars together, so I came down with IBS.
