A phrase said to acknowledge or point out a deafening silence.
In the 1980's film called Ferris Bueller's Day Off, a teenager called Ferris Bueller bunks off school. The
teacher reads out the roll call to monitor attendance. Since the lad is away, when the
teacher reads out 'Bueller', instead of hearing the response 'Here' - we hear a blast of deafening silence. The
teacher repeatedly says, "Bueller" which is followed by pure silence, again and again.
This highly repetitive section of a film, which us 80's kids watched repeatedly, then became the catchphrase that it has become today.
