Reference from T-ara. An ex T-ara member (that Queen's don't wanna claim) who was slacking and was a Karen towards hairdressers and stylists. Lied about the other 6 members bullying her during activities when she was fired from the group which damaged the group's reputation. Basically a person who acts like a snake. Can be used as a noun of someone who falsely accused someone else.
