"Dere type characters are characters that express their affection in different ways, or on different levels. Most of the dere types are how characters react to becoming lovestruck. What is Gire ギレ? The suffix "gire" (ギレ) is sometimes added to these personality words instead of "dere" (デレ). Its meaning in words such as tsungire, kuugire and yangire is that of "snapping" or "being mad" instead of "dere"'s meaning of "being in love". The word "gire" comes from the verb "kireru" (キレる), which means "to snap" or "to be mad (at someone or something)". Basically to be full of it. To lose your patience. To be done with. To have had the last drop. To burst with anger. To get the last string holding your anger down cut. That's what "kireru" means. The part of the word "kireru" that becomes the suffix is "kire", but it becomes "gire" instead because of a process called rendaku that changes the pronunciation of suffixes. The "gire" versions of personalities often have nothing to do with love or romance at all. People often attribute "-gire" as more violent versions of "-dere", but these two words aren't actually related, and could even be considered opposites. A character deemed "gire" doesn't necessarily need to be in a romance to be considered a gire type, they just lean towards aggressive, abusive, violent, dangerous and even murderous behavior. An example would be how a kuudere would show a sweet side ("dere") after their cold and emotionless side ("kuu") is broken. A kuugire would show an aggressive and dangerous side ("gire") once they snap and despite/because of their usual cold and emotionless state ("kuu")." -Dere Wiki
