A JAAS is a guy who thinks he's a TAAS but is just a weak, sad version of one. He'll never be as good as them and will cry about it.
Bro, you're a JAAS. You can't even beat your mom at poker.
He tried to be cool, but he's just a JAAS in a leather jacket.
Don't listen to him, he's just a JAAS with a bad haircut.
