Choknat is the name of a dog my family once owned when we lived in the Philippines when I was a baby.
My dad was in the US Air Force, stationed at Clark Air Base in the Philippines, where I was born. We transfered to Vandenberg Air Force Base here in California, leaving our dog behind with the housekeeper/caretaker. We made a home video which we watch every now and then, and my parents always said, "Say Hi to Tito Jun, Tita My, Tito Howell, and Choknat!!" In hopes, of course, that we would one day show the video to our loved ones in the Philippines.
It was a memorable and sentimental home video and has been since I was a child. The name "Choknat" stuck, and in 5th grade I created the AOL account Choknat57. Our AOL accounts were constantly renewed for free for a year or so (those were the days... I discovered pr0n at an early age lol) but eventually we lost our AOL access and went on to buy Comcast Cable.
The AOL account was terminated, so I created the AIM screen name "bloteshame" which still exists as my myspace, xanga, and deviantart accounts, none of which I still use frequently. (The story behind "bloteshame" is much longer than that of "choknater.") Some fool had changed the password to bloteshame, so the account was gone for good and I created bloteshame1, which lasted until about my junior year in High School.
A senior now, and a much more experienced smasher, I thought I'd adopt my well-known smash tag instead of bloteshame1 as my AIM sn. When I tried to create the sn, I saw that it was already taken. There was no way! I must've made it at one point but forgot that it existed. Turns out I made the account five years ago before bloteshame. When I got back on it, the password and buddy list were still intact with all my 8th grade buddies. A few of them still kept their old sn's as well.
A bit of nostalgia tied to my name, plus it sounds unique.
Pronounced popularly by smashers in norcal as "choke-nader" or "chock-nader."
Random trivia: I once went to a tournament in New York while on a vacation and I played against someone named samusexplorer. One of the members of DA was making fun of the names and writing the updated brackets on a paper plate, and my matchup was written as "c0cknat3r vs samuSEX" I beat him, then lost to DA Dav3.
