カクカク

• ローマ字: kakukaku
• 発音: /ka.ku.ka.ku/

意味

Choppy, stuttering, low framerate — describes jerky movement or poor performance in video, games, or animations.

An onomatopoeia describing jerky, angular movement, カクカク perfectly captures the visual experience of low framerates or choppy video. Originally describing physical jerky motion, it became essential gaming and tech vocabulary to describe poor graphics performance, laggy video playback, or stuttering animations. The reduplication (カク → カクカク) emphasises the repetitive, jarring nature of the stuttering.

例文

1. このゲーム、設定上げすぎてカクカクなんだけど。

3. 古いスマホだからアプリがカクカク動くのは仕方ない。
