Dooverlackies

A word that takes the place of an item or product that is difficult to name. Derived from a famous store people could buy things that couldn't be found anywhere else.

"You know, the place that sells those things, thingos, whatchamacallit, ahhhh....dooverlackies"

"You want what? Well, you've got two chances, DOOVERLACKIES and none"
