I went on a date and this guy introduced himself as Thunder. He said it was his nickname. Come to find out he had given himself that name.
In high school I asked to start going by my last name. My first name is Emily, and it was so common that it got confusing at a huge high school
My nickname in high school was Gus short for snuffle Luffagus the wooly mammoth from Sesame Street. Reason being I am uncircumcised so my junk looks like an elephant trunk and my friends thought it was funny and gave me that nickname
I gave myself the nickname Iceman when I was 10. Since then when my Dad called out "Hey Iceman" I had to empty and refill the ice trays in the freezer.
a friend of ours decided he would give himself a nickname "captain". He has his grandkids call him that along with his kids!!!
I'm so not kidding here...while in 4th grade the kid that sat next to me was CJ and I wanted something cool sounding cool so wanted to go by MC Horton...it was 1980
my name is Jessica. I had a friend call me Jessa, loved it, tried to get my other friends to call me Jessa. Did not succeed at changing my nickname.
