There's this thing called a dictionary, and it tells you the meaning of words and phrases. Try one, you might learn something. I'd hoped you might reference one before continuing to follow my obvious track, but I guess I overestimated you (never thought I'd appreciate B2K, but I do now).
Al Gore never said "The Presidency is a crappy office to hold anyway" after he lost, and this poster never said "Who cares if Microsoft is making headway, the POS market sucks so we don't want it." These are examples of proper usage of the phrase "sour grapes."
