Like a
snowball rolling down a mountain, growing ever larger as it continues toward the bottom, a wikipedia snowball occurs when one researches something on the wikipedia, only to then click link after link into
subsequent articles of interest until, suddenly, several hours have passed.
Jim: "I'm sorry I'm late, I got caught in a wikipedia snowball. I was looking for information on the new James Bond movie and suddenly four hours had passed.
On the bright side, now I know what happens in Marvel Zombies, I can tell you how astronomers
gauge the temperature of stars, and why
World War I started."
Jim's Boss: "You're still fired."
Jim: "Fuck."
