@LazarusACB you know what, you are right. i searched for the meaning and it turns out rice cake is used as a slang for "sex" in korean. taken from koreaboo, "Though the term may fundamentally be defined as, “sticky rice cakes”, the word is now commonly used as a slang term for “sex”, for when the certain sounds of pounding the batter to make rice cakes denotes the sound of two people having sex."
