5.
A term used to describe an underage girl used for sexual gratification. Usually a Korean girl, though any nationality can suffice. There are many underground Korean circles focused on selling yumyum to gentlemen, usually wealthy men. The price can range anywhere from 20$ to 1500$ and most of the yumyum are already trained to please in every way possible.
Gentleman 1: "My good sir, I highly recommend this yumyum circle to you, I was with a 12 year old girl last night named MiMi and you won't believe what she can do."
Gentleman 2: "Sounds excellent, I will have to check it out right away then."
