Kaiser Roll 

Used in response to someone that tells a story that isn't interesting, or holds little value to the audience. Also used when a story ends earlier than expected or is much less interesting than the build-up suggested.

Person 1: "Oh my gosh, so, this one time, I put a dollar in the vending machine and it ate my dollar... I didn't get any snacks"
Person 2: (after a pause) "Kaiser Roll"
