Mine is rather weird and goofy and long.
Back when I was still in High School and the Original Medal of Honor came out, my friends and I used to play it all of the time. Incessantly. One night, I believe it was New Year's Eve, we decided to replay the mission in which you have to sneak around a boat collecting passports while all of the Germans keep yelling "Your papers please!"
The accent was so bad and amusing, that as plastered as we were, we just kept shouting "Where are the papers?" The stupidity almost ended there, but one of the four of us passed out, so what do we drunkenly do? That's right, we keep whispering in his ear "Where are the papers?" Eventually he starts whispering papers in his sleep. WE all had a good laugh to that.
After that, my family finally got a computer and the internet. And I was attempting to think of an online handle, and my thoughts went back the papers incident. But I couldn't just call myself The Papers (though that would make an interesting superhero name: Don't Worry, The Papers Will Save Us) I had this strange habit of adding the word head after everyone’s name at the time. Jasonhead, Garethhead, Santahead....was just a thing. So I tack that on there, add a little pesto, some spice, some zip, finish with a monsieur title. And voila. We get the name of nameness.
