キレます（キレます、kiremasu）
- to loose temper

The Japanese word キレますキレます generally means "to lose one's temper," "to get angry," "to snap," or "to freak out." It implies a sudden outburst of anger or frustration, often accompanied by a loss of control or composure. It can also mean "to be sharp" or "to be cool" depending on the context, but the most common meaning is related to anger. The nuance carries an implication of a sudden, often unexpected, display of anger.

You would use キレますキレます when describing a situation where someone abruptly expresses anger or loses their temper. It's suitable for informal conversations and can be used to talk about oneself or others. It's important to note the context, since キレるキレる can be considered a strong word. It is more direct than expressing that someone "is angry" in a general sense.

キレますキレます is written in hiragana. The base form is キレるキレる. It can be written in katakana to emphasize the feeling of anger. The kanji form is rarely used, but when it is, it is written as 切れる. However, the meaning of 切れる切れる in this instance is different from the original meaning of this kanji, and therefore it is more natural to write it in hiragana. The okurigana is generally consistent; キレ plus the verb suffix.

This is the same root with the meaning of "to be sharp" or "to be cool", with the word キレるキレる meaning it's used in different contexts.
