“Done like a dinner”

To be “done like a dinner” is to be finished and utterly defeated. “We did him then, and I’m glad he’s done now: such a man as that ought to be done like a dinner” was cited in print in 1845. The saying has long been popular in Australia.
 
The saying has only infrequently been used in the United States. “And forget the damn Yankees. They’re done like dinner” was cited in a Boston newspaper in 1979.
