In one of the animes I've watched recently (can't recall the title), I heard words like "チーズ" (Not sure if this is how it's spelt in katakana since I only heard the word, but as for how its pronounced in English, it would most probably sound like cheeeeesee) and "をっと" (english pronounciation : wotto).
Judging from context, the former means "hello" and the latter, "whoops". And there is also "うわあ" (uwaa) which prolly means "yikes" (im guessing, in a bad way, simething like "やばっ") in English.
So the questions that arises are, since I am only translating based on context, I am not sure if they mean what I think they meant. Can anyone correct/ advice on this?
Secondly, are these words even used in real life (I have only heard them on anime) ?
