Other forms: crinkled, crinkles, crinkling
To crinkle is to form small folds and wrinkles. Eyes crinkled, crinkled paper, crinkle at the edges.
Eyes crinkling at the corners is the mark of a genuine smile — the muscle involved is hard to move on purpose, which is why a false smile misses it. Of paper and foil it means fine irregular folds. Note that the word comes from an Old English verb meaning to yield or bend.
