"man, ive been waiting here for you about a brazillion years, jeez
"OH NO!" the President exclaims. "That's terrible!"
His staff sits stunned at this display of emotion, nervously watching as the President sits, head in hands.

More loosely, any time only the upper digits are given of a hexadecimal address, "brazillion" means the the rest of the 8 digits are zero or are not important.
