Defines a woman aged over 40 who is well past her shag prime, but still eager to get laid (ideally by a younger and more financially successful male). This woman probably shagged most of Def Leppard, Poison,Motley Crue and Metallica back in the 1980s and could be old enough to be your Mum.
Back in the day, a top quality knocker but now her tits have sagged and her vagina is more open than the Schengen Area of the EU. Hence the term 'Expired Lottery Ticket' - you shouldn't want to cash her gash.
Donna is such an expired lottery ticket - she craves any young guy with a dick and a job despite being close on to 50!
