A round bunny with long ears. The ⌒ curves on each side of the face are arching bunny ears — the kaomoji convention for long, drooping rabbit ears (as opposed to triangular cat ears). Inside the parens, = and = on each side are flat closed-content eyes, and ∵ is the “therefore” mathematical symbol used here as a bunny nose-and-mouth (the small dots form a tiny pink-nose-plus-mouth pattern).
The ⌒ ear convention is the cleanest way to signal “bunny” in kaomoji — no other animal kaomoji uses it. Combined with the ∵ nose (which has a tiny triangular bottom that resembles a rabbit’s split upper lip), the result is unmistakable. The flat = eyes give the bunny a sleepy, content expression.
Use it for bunny-related content: photos of pet rabbits, Easter posts, cottagecore content involving rabbits. On Instagram it pairs with Easter or spring-themed posts. On Twitter/X it suits soft pet content. On Discord and TikTok comments it lands under bunny videos or anywhere a rabbit-mood fits (also works for “hopping” or “bouncy” abstract energy). It can decorate end-of-message punctuation in a soft register.
In Japanese the matching word is うさちゃん (usa-chan — “Mr./Ms. Bunny”). Pair with phrases like かわいいうさぎ (‘cute bunny’), ぴょん (‘pyon’ — hop sound), or もふもふ (‘moffu moffu’ — fluffy onomatopoeia).
