You won't believe me, but Japanese have no really great way to curse. Yes, there are informal ways of speech that can get you into fights and there are kind of semi-curse words, but the real curse words such as S*** D*** really don't exist.
From this point on it will include curse words. If you are deeply offended--don't read it. =P Though I have no idea why you clicked the link if you are that offended.
Examples:
しまった Shimatta- Darn it. (Anime-only) It does not mean "Shit"
がき also (ガキ) Gaki- brat (It's not bitch)
ばば Baba- Witch, hag might slightl
