Translation guide
An English vulgar insult expressing anger, frustration, or contempt. Japanese has no direct equivalent; the best choice depends on context, intensity, and the speaker's relationship to the target.
You want to insult someone directly in anger, similar to 'You bastard!' or 'You son of a bitch!'
Literally 'this guy/bastard'. A very common, rough, masculine insult. Strongly confrontational.
You son of a bitch, I'll kill you!
What the hell are you doing, you son of a bitch!
Extremely rude 'you'. Often used alone as an insult. Very aggressive, masculine.
You son of a bitch, how dare you do that to me!
Adds 'shit' (クソ) for extra vulgarity. Very strong insult.

Literally 'stupid bastard'. Common insult, slightly less vulgar than クソ野郎 but still strong.

Do not translate 'son of a bitch' literally as 雌犬の息子 (めすいぬのむすこ). It makes no sense as an insult in Japanese and will cause confusion.
son of a bitch (literal, nonsensical)
Most Japanese equivalents for 'son of a bitch' are rough and masculine. Women rarely use 野郎 or てめえ. In polite or formal settings, these words are completely unacceptable. If you need to express strong displeasure politely, use phrases like 許せない (ゆるせない, 'unforgivable') or ひどい (ひどい, 'terrible') instead of direct insults.
When talking about a third person you're angry with, Japanese often uses the person's name with a derogatory suffix like 〜の奴 (〜のやつ) or simply あいつ. This can convey contempt without explicit vulgarity.
That son of a bitch was late again.
I was tricked by that son of a bitch.
Informal 'that guy/he/she'. Can be neutral or derogatory depending on tone. Less explicitly vulgar than 野郎.
It's all ruined because of that son of a bitch.
Very strong, vulgar. 'That shitty bastard'.
I'll never forgive that son of a bitch.
Son of a bitch! I lost again.
Literally 'damn it' or 'beast'. Common exclamation of anger/frustration. Slightly old-fashioned but still used.
