Nick Names

I met a my college friend Arun Kumar after 6 years.
Last week he was here in winston-salem, NC for his business trip.
We went to a same school for our four year Mechanical Engineering

Actually in our friends circle no one knows him by his name.
He is very famous with his nick name "Proxy". We were talking about how he got that name.
In our first year we had a chubby lecturer for our Basic Electrical paper, Geetha Madam.
In our attendants list the next name to Arun Kumar is Antony Praveen Kumar(well known as DAP)

One fine day Geetha was going through attendants list, "Arun Kumar" he said Yes ma'am
Antony Praveen Kumar, he said Yes ma'am with the same tone. She got him. From that day, he has become "Proxy".

The other main reason to use nick names is to differentiate the guys with common names. For example there were four "Karthik" in our class. So to differentiate everyone uniquely we used nicknames.
"Self"Karthik ---> My nick name. I ragged my co-students in the first year, called self ragging.
"Mama"Karthik --> He is a very big guy........so, Mama(Uncle)
"Kalingan"Karthik-> I'm not sure why he got this name, but "kaligan" is Goundamani(Comedian) name in Ullathai Alitha-a tamil film
"Tuticorin"Karthik->He is from Tuticorin

Other interesting nick names in our college
