<p>Referring someone as 大哥哥 (big brother) to a kid is not unlike referring a "狗" (dog) as "狗狗" (doggy) to a child. It is a kind of 'baby/ kid talk'</p>

<p>大哥 is a proper term for "big brother". Just like in English, depend on context, 大哥 (big brother) can mean your own elder brother, your lover, a stranger who is older than you or about  the same age as you and so on </p>

In Triad lingo, '大哥' can mean a gang leader too :-)

<p>The differences between 大哥 and 大哥哥 in this context is the age difference.<br>
大哥哥 here probably looks under 25-ish years old, and seemingly a friendly person.<br>
大哥 if used here would refers to any adults who are older than 小明</p>

"大哥哥" is broadly used when calling any young male but older than you and not a relative.</p>

大哥 means: 1. The eldest brother in one's peers. 2. The boss of a gang. The address of reiterative diction in Chinese, like 哥哥, is often used by kids or juniors, compared to 哥. If the style is used in persons' name, it makes a nickname.
