The codename given to an unattractive girl who will show up to parties after all the alcohol has been consumed and proceed to try to hook up with the guys who would never give her the time of day otherwise. In a drunken state these girls will not appear to be ugly, therefore earning them the title sneaky sue
pete:man, lawrence was hammered last night.
me: dude did you see that fat chick he was making out with last night?
pete: yeah man she was definitely a sneaky sue.
me:damn he always gets sue'd.
