Its what happens when you come to UD to search a word, but get hooked into all of the new 'word of the days' and by the time you finish reading them, you have forgotten what you were going to look up.
In more extreme cases you forget you were even going to look up a word.
1. "Damnit! I forgot what I was going to search! I'm having Word of The Day Amnesia! Hmm let me switch back to the facebook tab and see if the word is there."
2. "Those were some pretty funny 'word of the days', oh well back to youtube..."
"word" originated from a gangsta' who at firstsaid "word" as a sign of affirmation, however most other gangstas thought this was stupid, and they decided to keep it gangsta by popping a few caps in that nigga's ass.
these very gangstas then looked upon the original sayer of "word" as an idol, for having been shot.
forever after other gangstas used "word" as a "yes."
