How can I express this in English? How can I express the sound or effect of rubbing your skin or something smooth and hard like a waxy floor in English? In Korean, this can be expressed as "뽀드득뽀드득(ppodeudeuk-ppodeudeuk)", but I don't know in English and also I haven't seen any expression of it in English. For example: "You should wash your skin until it __________." (makes rubbing/brr-ing sound?) "If your feet get sweaty, then you can feel __________ in the shoes." (rubbing/brr-ing feeling?) Thanks!
