FYI
“可恶 kěwù” is a Chinese slang phrase that can be translated to “hateful/annoying!” or “Dammit!” It’s a way of expressing extreme frustration or anger towards a situation, behavior, or person. For example, if someone cuts in line or does something selfish, you might say “太可恶了!” to show your disapproval and frustration.
The phrase can also be used playfully or exaggeratedly, such as when you’re joking around with friends or exaggerating a situation for effect. For instance, if your friend posts an Instagram photo about the many luxury gifts she received for her birthday, you could comment “可恶!好羡慕!” (kěwù! Hǎo xiànmù!) to express your playful envy.
