Twitcher

Twitcher is a famous social network from Mom Store. Lots of people are addicted to Twitcher and often upload videos in it. Mom programmed a Twitt-worm to control the mind of all Twitcher users so they buy the new eyePhone 2.0 once a user reaches his one millionth follower. Both Bender and Fry had one million followers, so millions of zombie people walked into Mom's store.

Trivia

 * "Twitcher" could mean "contortionist", but it could also be a reference to a different pronunciation of, per example, "twit you", that will sound like "twitch you". It could also be based on Twitter.
