Mine is actually my nickname offline. It developed over the years, but Smitty was a nickname given to me way back in middle school by my sixth grade teacher and it stuck and then Longsleeves came later, in about ninth grade when joking with friends about how I loved longsleeve Heavy Metal t-shirts so much I would call myself "Smitty Longsleeves" and my friends thought it was awesome. Said it sounded like a knight, or a dragon hunter, or some medieval type nobleman, so I kept it as back then we were trying to start a band and I thought it would be a cool stage name. Now, years later.. the nickname stuck lol.
