@Monquito:
It a 100% doesn't mean crewmate.
And again, you're mixing up series with real life stuff.
Ok now, you are breaching the realms of retardation. The real life stuff IS ALSO THE SAME. The reason it's translated to crewmate in English is because it's the word that fits the Japanese word. If you understand translating from Japanese to English or vice versa, you will find that there are words and phrases you cannot directly translate.
NOBODY in Japan uses the word Nakama to refer to a friend or a just a person you are cool with.
Hell, I even did research online to even show you:
"t's a question of degree. 友達(Tomodachi) is pretty much anyone you hang out with on a regular basis; 仲間(Nakama)is a much closer relationship, almost like 'someone you choose to share your life with'. 仲間(Nakama) also seems to have a sense of 'doing things together' or 'working towards a common goal' which is absent from 友達(friend)
The context of shounen manga gives a nice demonstration of one boundary between the two. The protagonist's 仲間(Nakama) are in effect the other main characters - the people that travel with him and work together with him to do whatever it is he's doing. His 友達 are all the other people he knows and likes - the ones that he'll hang out with if he comes across them, but they're not constantly with him and they're off doing their own things.
It's a distinction English doesn't make, so it's hard to think about when you're not used to it."
仲間( Nakama): People who share the same goal and work/struggle/fight together in a group or organization.
友達(tomodachi) A friend. Something based on personal feelings of intimacy or affection. You don't have to do something special with your 友達. They can be someone you haven't met for a long time.
You really need to stop being stubborn, you're entering a completely different ballgame when you get into Japanese. It doesn't work the same way as English does.

@Razh:
Two main reasons why I thought Jinbe could join.
1. SH lack token fishman.
2. SH need at least one more powerhouse to join them, seeing how enemies are getting stronger and stronger.
Having him properly introduced just solidified the thought.
It's not like it's a completely random prediction, either.
This is why I don't see carrot joining.
Because she is the traitor She's not that strong, haven't even seen any Haki from her, what could she possibly add to the crew? We're at a stage now where Luffy is going to need people like Jinbei and that can add something to the crew. Not carrot waiting for her Sulong once a month.
Unless you can somehow create a moonlight device and go Sulong any time you want.
