What is Superthread?
1.
A topic on an internet message board with a large number of pages and posts (usually considered anything over 10,000 posts). Superthreads can vary from being focused around a certain topic, to being a thread where people will talk about whatever they deem worthy at the time.
Dude, did you see that superthread where that guy posted a screenshot of his desktop with the shemale video folder on it?
