Loosely tranlating to "older brother" or "big brother".In common Yakuza (Japanese Mafia) slang, "Aniki" is a term used for a Yakuza of older, or senior rank within the family, and is said as a title of respect from a lower ranking family member to a higher.
I refer to him as "Aniki", because he's the leader of our "family".
