To fold, wrinkle, or crimp; to create ridges or irregular folds in something.
Possibly a frequentative or variant of crimp, or from a blend with crumple (to wrinkle). The -le suffix sometimes creates verbs expressing repeated or intensive action.
Crimple might be dialectal or archaic, but it captures something crumple doesn't—the idea of creating regular ridges rather than random wrinkles.
