A goon slut does not have to be sexually active.
The term 'goon slut' was first coined by a genius northcliffian after he witnessed the affinity two particular Perth females had to cheap alcoholic beverages in particularly Goon. He noted that they often prefered the company of goon to that of a gentleman and ritually would administer the beverage via a funnel. This practise would render them motionless or abusive within two hours of drinking.
eg: lucky goon can't transmit infections or she'd have died from AIDS long ago.
