4Chan, the popular message board everyone from Rick Astley to Time Magazine loves to hate, is reportedly the reason the odd phrase "#gorillapenis" has shot to the top of Twitter's Trending Topic. The genital infiltration is being referred to as "Operation Sh*tter."

The phrase has since disappeared from Twitter's home page, but the term is still searchable. Late last week #mrsslocombespussy shot to the top of the list after the death of former BBC star Mollie Sugden. Twitter denied censoring the phrase, instead chalking it up to a bug that won't let users search for hashtags longer than 16 characters.
