Recently I came across this acronymn EKSI being used widely in forums (Later I realized it was only used by those who know tamil). I had no clue as to what it means and googling does not reveal anything obvious.
Finally I had to ask one of those guys who used this and it turns out to be the abbreviation for the most famous tamil dialogue 'Enna Koduma Saravanan Idhu' --- EKSI :)
For those who don't understand tamil, this is a dialogue said by actor Prabhu to actor Rajini Kanth in the film Chandramuki (tamil). This dialogue became so famous and is used in various contexts generally to insult a work in a humorous tone :)
Watch the original clip and actor Prabhu's reaction: LOL!
