thugdere means: Thugdere refers to someone who is primarily a woman character but it can sometimes be applied to men. They often abuse their lovers, often emotionally or physically, and can be very affectionate towards them. Thugness is often used to hide their caring and loving sides, making them appear weaker or more foolish. This should not be confused with the yandere, kuudere or tsundere.
