crinkle
Crinkle (verb) means to squeeze or bend something so it gets small, uneven folds.
Etymology
Came into English via Middle English crenclen ("to bend, buckle"), from Old English *crinclian, a frequentative form of Old English crincan ("to yield"), from Proto-Germanic *kringaną ("to turn, to fall, to yield"), from Proto-Indo-European *ger- ("to turn, wind"). It is cognate with North Frisian krenge, krönge ("to obtain, reach, attain") and Dutch krinkelen ("to turn, wind"), and is related to cringe.
