寝ていただけなのに怒られたパンチくんの一日

What does “ぐっすり” mean in Japanese?

ぐっすり (gussuri) is a gitaigo — a Japanese mimetic word that captures a state rather than an actual sound — meaning “deeply” or “soundly,” almost always describing sleep: ぐっすり眠る/寝る, “to sleep soundly.” Japanese has dozens of these sleep-related mimetic words (すやすや for peaceful light sleep, ぐうぐう for snoring), each carrying a slightly different flavor no single English word fully captures.

In the clip, an animal is shown ぐっすり眠っている (soundly asleep) right before another animal wakes him up and, confusingly, scolds him for it — the narration leans on ぐっすり specifically to make the ensuing injustice land harder: he wasn’t dozing lightly, he was properly, deeply asleep. Swap in すやすや for a gentler, more peaceful connotation, or ぐうぐう to emphasize the sound of snoring rather than the depth of sleep.
