LOL she asked for a short explaination NOT the elaborate history!I just thought about my initials which are S.A.M., then I was like "hey, that sounds like Sam!". so that became my nickname like two years after I found out. Then I started playing Pokemon, and coincidently, both my OT# in my pokemon FR game ang my DP game was 40400, then once, i was in search of an electavire, so I put my nickname and my average OT#in those games, and got Sam40400! cool story huh? well not really but who cares?!
