Bastard
noun
Ugh, that field guy. He's the worst. Always in the fields, making us look bad, quite the bastard. Really though, he's just this guy, but for some reason I sometimes don't like him.
While 野郎 can be a casual term for a man, it's usually used to insult or show annoyance towards someone. So it's best to avoid using it unless you're really sure it's okay!
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
あの野郎の物の言い方が気に入らねぇんだよ。
