-Heavy usage and abuse of the words "fail", "epic" and "win"
-Even heavier usage of overused memes from 2004-2006 such as "pedobear", "trollface" and "u jelly/mad?"
-Improper use of the late-80s early-90s term "troll"
-Using the "Awesome.jpg" emoticon from the SomethingAwful forums
The people who use this brand of humor or think it's funny are generally those who have discovered 4chan within the past year or two and feel the need to regurgitate everything they see on the site in order to fit in or to pretend that they are funny regardless of the originality of the content.
