When there is no answer to a given question, the questioner may highlight the fact that he has had or is expecting no reply by saying, "Beuller". This is normally an internet forum occurrance, but can also take place in everyday conversation.

Originally from the cult classic movie "Ferris Beuller's Day Off" in which the eponymous hero is absent from school and his teacher, while taking the class register in a deadpan voice repeats "Beuller? Beuller? Beuller?" over and over with no response.
Anybody know where the forum mods went?
