no can do

I can’t do what you ask; this cannot be done. This slangy expression is derived from the pidgin English antonym can do, picked up by sailors in the Far East and soon turned around. Although the earliest citation for it is dated January 4, 1906 (“No can do Johnny, no can do. . . . Him gloatee too muchee lolry,” Independent, cited by Random House Historical Dictionary of American Slang), Eric Partridge believed it dates back to 1850 or even earlier. Both positive and negative versions were widely used in the military and soon spread to civilian language.
