I don't know what's worse - the fact that you need to look this word up or the fact that it was created in the first place. in any case you should shoot yourself in the face.

A stupid way of spelling "cool". Made up by morons.

Internet slang and spelling for the word "cool"

Kewl is the swedish word for describing something/someone funny.
Probably copied by random people who thinks it's pronounced 'cool' and then used it as if it meant 'cool'.
Later, people got annoyed of it and made themselves look like shitheads by defining it on Urbandictionary.com. The same people later gave this defination a thumb down because they felt offensed by it.
And even later, this defination got deleted and no one could read it any longer. But by then, no one cared.

The stupidest possible mispelling of a word in existance. Not only is it wrong, but it is also harder to type than "cool".

The way some internet users spell the word "cool". May be also concidered a part of 1337 speech.

a kewter, more klever, kewler way of saying 'cool'

A completely unnecessary and moronic variation on the word "cool". It's harder to type than "cool" and makes you look like a retard if you say it.
