I actually made this name 15 years ago when I was a teenager and my friends were into "tagging" (graffiti). My friends had weird "tags" and I wanted mine simple, my initials to my name...
Richard E. Calvache and my birthday Feb 13. I never "tagged" that name but when I got into the internet faze I started to use it as my handle. It wasn't until I was playing lazer tag in the city when an employee called me REC 2-13 as in the number 2 pause 13. I loved how it sounded and now I love that I'm known as it.
