It's a meme. People say cool story bro to mock whoever they say it to. Meme- a fad on teh interwebz. some are called "forced memes". these do not cause many lolz. teh original memes are teh lolz. Example: "One does not simply walk into Mordor." Thiz meme is teh quote from "The Lord of the Rings" movie trilogy. Example 2: "Bronies" These are teh grown ups who enjoy watching My Little Pony: Friendship is Magic on The Hub, they call themselves 'bronies' because bro/pony=brony. The average age for a Brony is 13+up. Female bronies are regardless, called bro/ponies because of their cool and awesome nature. But the technical term for women who like My Little Pony is "Pegasister". The average age for a Pegasister is 13+up also.(Pegasus/Sister.)
I am a female Brony.
There are many memez in TEH interwebz, but some are just creepy. Example: CreepyPasta/ZALGO- the goal of these are to mess everything up on teh interwebz. And make them creepy as h?ck. Example: Smile.jpg. This creepypasta features a dog with human characteristics, such as a biiiig human mouth flashing it's red teeth, and a bloody human hand in the really red background. This picture was in a chain letter in the 70's, with a message saying "SMILE!! GOD LOVES YOU!!!!1!" Creepy factor: 8/9. It's a true story; and the hand in the background caused some people to commit suicide. They say if you don't spread the word, SmileDog comes in your dreams. Until you kill yourself. The real picture of smileDog is nowhere to be found, except for some simialar ones floating around teh Interwebz. There's lots of memes in teh universez. TEH ENDZ.
