Kewl is another way to say cool, but its not as kewl. Other ways to say kewl are: Coo-well / Kewull / Koo-well / Cuu-wull...etc

but it cannot be: cool.

Most often used when describing something interesting or suprising...or just downright kewl.

There is also a hand sign for this. Here's how to do it:

First make a fist. Then raise your pointer finger and your pinky straight up. Now bend them halfway so that the top of the middle part of those two fingers is flat. Keep your thumb bent in like when your making a fist! and thats it...
Taylor: wow look at this M&M! It has 2 peanuts in one!
Jeanne: Wow thats sooo Kewl!!!

Kristin: Hey do you like these glasses?
Taylor: Ohhh yeahhh those look super Coo-well. Get them!
Kristin: Okay yeah Kewull girly.
