my name's jason but when we were kids my li'l sis pronounced it as "jahson" so it kinda' stuck with me...i put the "x" at the end to make it sound somehow cool just like the name of that big blade wielding horror flick character!
When i was a F.E.A.R multiplayer addict , my name was Kazanova xD (freaky i know O.o) and then i remembered some word like Sensanaty... and then i thought of Sensanaty... at first i thought it ment something xD and then i saw it didnt :P
