1.Shasha is how you would describe a girl that means the whole world to you, you would do anything to keep her because you just know shes the one, extremely beautiful girl in every way(personailty and actual beauty). A shasha is one who keeps her man happy without even trying. In other words a shasha would be the the perfect girl for a man.
friend: are you ever gonna dump your girl?
guy: NO! are you crazy?! shes a shasha. im probably going to marry her.
