Nadigiri- the silver Jubilian slang

"Nadigiri":- Does this word a ring a bell in you ears?

Most of you may not be aware of this word! Unless you are a Tamilian/malayali! I knew this word as part of the late south Indian actor- Sivaji Ganeshan's title-Nadigara Thilakam! Wait- if you are from Silver Jubilee Govt College(Kurnool, AP, India) during 80s/90, you would definitely be familiar with this word as the campus used to buzz with this word. Silver Jubilees fraternity of that time used to call a person doing Nadigiri if he was doing some over action or acting as smart alec. Seniors of that time used to call their juniors as Nadigiri. Classmates used to call each other Nadigiri. I really dont know the exact meaning of the word. But I can relate to that and say that it may mean "fine action". But in Silver Jubilee Slang it means over action. If you end up calling Sastry (me) doing Nadigiri for making frequent and obsessive posts on Facebook, you have understood the word the Silver Jubilian way! You may also like to suggest the Telugu/English lexicographers to add this word to add this word to the respective dictionaries. Sounds preposterous? What does your campus lingo say?
