Oh I see. That's pretty cool man.
Unfortunately, my name doesn't have an amazing story that lives up to how funny it is because the guy that comes up with this stuff just does this sort of thing off the top of his head.
You see, one day I was enjoying some OJ (not the glove guy, the drink that happened not to be spiked today, which was a real shame after what happened but I digress...) and talkin to the aforementioned friend, when all of a sudden, I think he said something hilarious and I spilled the drink on my lap. This, as you're probably assuming, left a rather large stain in the general crotch area. Of course, the first thing this joker would do would be to laugh and say "oh look, it's doctor peepee!" Fortunately, the name didn't stick, but that was the least of my worries anyways as I had to go throughout the rest of my day attempting to convince every single person in middle school (kids were a pain back then) that I did not piss myself.
So there you have it. If that wasn't good enough for you, then I'll just end with a few of the other names that he left me with: Mario, Mustachio, Mr Highwaters, and of course, Spanky Fajia.
Peace Mask.
