uto-uto
That drowsy state where you keep nodding off and snapping awake — on the train, during a lecture, after lunch.
💡During a long afternoon meeting — 'I started uto-uto during the presentation.'
授業中にうとうとしてしまった。
I dozed off uto-uto during class.
The warm lecture room made me ___ at my desk.
暖かい教室で、つい○○してしまった。
