Any annoying brit man or woman that likes to talk derogatory about Americans and their pleasant demeanor. Their lackluster personality and food encompasses this name. You're not a limey anymore, you are a cunt biscuit.
Ugh so sick of watching these cunt biscuits talk about Americans on tiktok.
Basically Kim Kardashian. A person who enjoys having any type of sex with more that five people. They are called a biscuit because all they are good for is fucking and eating.
I caught my girlfriend cheating with seven other people. She's such a cunt-biscuit.
