A scale in determining the drunkeness of a girl in a bar. 1 is stark raving sober and 10 is Lindsay Lohan.

Its used to determine if a girl in a bar is too drunk to try to pick up.
That chick is a solid three on the Lohan Scale.

No way shes swaying too much and is covering her face when she laughs. Id say shes a good five on the Lohan Scale.
