As the title suggests, here be the trash-talking and nick-naming Sanji and Zoro do in One Piece. It's what they're famous for. They are pirates after all. Even so, the insults are not at all harsh, except mebbe for kuso and yarō :).

The following are not insults though they can be used in an insulting or rather rude way :) Behind these you'll often hear -ra or -tachi which makes it plural. The second is more polite than the first.

手前 temē
"you", more impolite than omae
こら kora
it's an interjection meant to scold or reprove someone or to call out to someone, meaning roughly, "hey!".
お前 omae, omee
"you"; more impolite than anata
彼奴 aitsu
she, he, that girl, that guy
奴 yatsu
she, he, her, him
此奴 koitsu
this person, she, he
君 kimi
you; buddy, pal

Note : ラブコック rabu kokku - love cook was originally coined by Usopp (# 22), who also insults Sanji from time to time.
