A form of minor amnesia for when you inexplicably experience the burning urge to look something up and immediately rush to the proper website to look something up only to forget what you wanted to search for.
I was falling asleep on the couch one night, when suddenly, a random thought popped into my head. I rushed to my computer and brought Google up, but by the time I was ready to search for anything, I experienced Webnesia.
