O l d L a d y :
The wife or commited girlfriend of a club member. Being considered an old lady means being under the protection of the club and earning respect from club members, depending on the position of the club member they are committed to, and jealousy from sweet butts and crow eaters.
Examples: Gemma Teller-Morrow & Tara Knowles-Teller
C r o w E a t e r / S w e e t B u t t :
A woman that clubs let hang around the bars that they occupy and serve them. They are expected to do whatever club members ask them to, usually to get them a drink or to clean, but it can include intimate relations. It is the hope of the sweet butt/crow eater to be noticed and become someone's Old Lady.
Examples: Rita "Cherry" Zambell & Wendy Case
