<b>5000</b>
(interj) A farewell bidding, from 'I'm outta here', which evolved
to 'I'm Audi', and to '5000' after the Audi 5000 car,
which got recalled and is a rare sight nowadays. 'Yo, we outta
here, 5000, G!' -- Ice Cube and Flavor Flav (I'm only out for
one thang [1990]).<ul><li><a href="http://www.radio101.it/soul/dictiona.html">The Totally Unofficial Rap Dictionary</a></li></ul>
