Each post published on 4chan bears an identifying number, assigned consecutively by order of publication. Because of the huge number of posts published every day, this number is practically random. 4chan has an old tradition of users trying to have their posts obtain certain special numbers, known as “gets”. The most precious “gets” are round numbers (such as 1m) or those that repeat all their digits. By October of 2015, /pol/ was approaching its 77777777th post, seen to be of particular importance because the number 7 is often associated with good luck and fortune. The post that would “get” that number was sure to gain legendary status within the community.

As it happened, the 77777777th “get” was for the message “Trump will win”.
