oof 在英语口语里是一个语气词。
例如：
A: “Oh, I forgot to bring my assignment! It's due today!"
B: "Bold of you to assume I've done it."
A: "Oof!"
翻译过来就和“oops"的意思差不多，通俗一点讲就是“哎呦”的意思。
同义词：oops
意思：（差点出事故、摔破物品等时说）哎哟，（做了令人尴尬的事、说了无理的话或泄露了秘密等时说）哎哟
例如：
1、（差点出事故、摔破物品等时说）哎哟 used when sb has almost had an accident, broken sth, etc.
Oops! I almost spilled the wine.
哎哟！我差点把酒洒了。
2、（做了令人尴尬的事、说了无理的话或泄露了秘密等时说）哎哟
used when you have done sth embarrassing, said sth rude by accident, told a secret, etc.
