A variation of dibs. A girl referred to as "dibs" is usually very attractive, and a "scribs" is usually very unattractive. In extreme cases of "scribs", the term "GOO!" is used. This scale, originating at Vanderbilt University, was created to distinguish between "dibs" called to refer to hot girls and "dibs" called sarcastically to make others look at someone they otherwise wouldn't. Also related: dibs-scribs continuum (the hazy scale between the two)
M1: Total dibs on her!
M2: Are you kidding? She's a complete goo!
M3: Damn, she's so bad she ain't even on the dibs-scribs scale!
