Urban Amnesia is a symptom often experienced by curious people who hear a word and need to look it up.
It occurs when, in a public situation, someone hears an
interesting word and doesn't want to look like an idiot and ask what it means. At that
time, thinking to themselves "I'll look it up on
Urbandictionary later!" then, upon reaching an internet source, you experience a total blackout and cannot remember the word you were going to look up.
