Mine is too long and stupid of a story but here goes since most people probably think I'm an idiot with the username I have...
I've wrestled all my life. I still coach. I am an assistant wrestling coach at one of the best non-DI schools in the country.
Back when I was in college, my friends and I used to go play NTN Trivia at a bar on Sunday nights. They had $1 bottles of beer. When you play trivia you only get 6 letters for your handle. So I couldn't enter in GRAPPLER. I shortened it the best I could to GRAPLR.
When people reply to my messages, I often get G R A P I R since the lower case L looks like an I. When I used to play poker online many people figured it out and asked if I was an MMA fighter. (I'm not but many of the guys I wrestled with are or were)
The name/handle just kind of stuck for my online stuff. Stupid, I know since I'm not limited to 6 letters elsewhere, but oh well...
