Ha!
It's a casual term for storing and propagating the various yeasts that you'll use for beer.
(worst case) If you get a lower gravity/lower alcohol kit for an ale, like a british mild and choose one of the fancy Wyeast or White Labs liquid yeasts the yeast will be ~25% the total cost.
Funny thing is that, unlike the malt/grain and the hops, you finish each batch with far more yeast than you started. Just wash that yeast from the trub/hops/other crap with some sterile water and you're in business!
