It means uncle, although in anime character regularly use it in its less formal form where it functions more as "mister" or "sir." It's just an informal, but not necessarily rude, way to refer to an older man than yourself that you're unfamiliar with.

That's all I wanted to get clear. Most definitions stop at uncle and barely explain the secondary, and probably more common, use for it. "Ojisan" always means "sir/mister" unless they're actually they're uncle.

"You dropped your wallet, Ojisan" = "You dropped your wallet, mister/sir."

Ojisan literally means Uncle in Japanese.

Can also be used as a slightly impolite way to address a middle aged man, similar to the English "Mister".

My Ojisan is visiting from Osaka tomorrow.

Hey Ojisan, keep your hands off my girl.
