puckeryoudaoicibaDictYouDict[pucker 词源字典]
pucker: [16] The etymological notion underlying pucker seems to be of forming into ‘pockets’ or small baglike wrinkles (the same idea led to the use of the verb purse for ‘wrinkle, pucker’ – now dated in general usage, but fossilized in the expression purse the lips). The word was based on the stem pock- of pocket.
