A dude named Steven who is cooler than your average Steven. He's either more funny, more attractive, more intelligent or all of the above, in comparison to a regular Steven. However, if a Steven refers to himself as a Shhhteven, he in turn becomes the opposite: less funny, less attractive, less intelligent, and most likely all of the above, in comparison to a regular Steven.
Alternate pronunciation: Shhhtephen.
"Oh my God Becky, he's not just a Steven. He's a Shhhteven!"
…
"What up? I'm Shhhteven."
"Uhhhh..yeah, lame."
...
"Hey Shhhteven, lookin' good today... haha you're so funny and attractive AND intelligent!"
