Quotes
"Last night—at dinner"—Mrs. Appel eyed him accusingly—"I found—an eyewinker—in the hard sauce."

-- Stewart Edward White, Gold, 1913


Origin
Eyewinker is a very rare noun, originally Scottish and now mostly an American regionalism. Eye needs no explanation; winker has several meanings: "eyelash, eyelid, eye, something that gets in the eye and makes one blink." Eyewinker entered English in the early 19th century.

[Dave Poor]

I've heard it used, and used it myself, to refer to a statement that needs an eyewink accompaniment.

[Marshall]

Much better than a buttwinker.
