Anime Convention Humor

The proper name for the brand of humor used by chantards and anime convention goers. Anime convention humor consists of:

-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.

Examples of Anime Convention Humor:

Chantard 1: Haha that was so epic win lulz!
Chantard 2: Yeah pedobear for the win epic lulz all around!!
14-year old female anime fan: Haha trollface.jpg!!!!
Chantard 1 and 2: TITS OR GTFO EPIC WIN LULZ!!!

Anime Convention

A place where, no matter what you do, you will not be the biggest dork around.

Last weekend, Julie and her friends attended an anime convention, and found themselves presently surprised that many other con-goers had much worse wapanese-syndrome than they did.

Old Guy Convention 

When a bunch of old guys gather at a McDonalds, IHOP, OCB, or mall food court to eat breakfast and bullshit for a long period of time. Only groups of 5 or more qualify, as this signifies that at least two transportation vehicles were used and a greater level of coordination was involved. I know you can technically fit five people in a car but would an old guy ever ride bitch? Since the elderly enjoy pattern and familiarity, these conventions can occur weekly or even daily in a single local.

You'll never get a seat at McDonald's on Thursday mornings, the whole place is an old guy convention.
