None. It is a completely strange word for us, our words normally doesn't end with a consonant (never with a 't') and we don't even use 'k' in our alphabet. I guess not even Google knows why it went so viral here. A proof of that is that now Facebook is by far the most used social network here (Google didn't even try to make Orkut -> GooglePlus transition, I don't know why).

Google handling of Orkut just suck. Personally the features on Orkut are much more interesting than the ones in Facebook, but Google never fixed issues that existed since the platform inception ( for example there are no edit button to fix your forum posts )

Social networks are not much about features, or minor things like slangs.. they are about friends, and people using it..

i start to use it in 2004.. i guess facebook was not even dreaming to born.. i guess i've stop to use it in 2008.. too many people.. to many noise.. and stop for the same reason that now i dont use facebook anymore..

is interesting with few early adopters friends.. (they have a high intelectual standard in median) .. but then.. everybody start to use it and say every #$% they are doing..

theres nothing magical about who get the top on the list.. they were there, in the right time.. and got the right sort of luck :)

Fun fact: Orkut is slang for "orgasms" in Finnish

Kut is dutch slang for vagina, though.
