(n) When you start looking something up on wikipedia (usually something meaningful for a class or work) and end up clicking link after link of related topics in each article, until you've ended up on something completely unrelated and wasted a large amount of time on information you forget 1 hour later.
I started looking up micro albumin but went on a three hour wikipedia journey until I ended up on anal intercourse.
