So what happens when he gets older? Does it change to "Old quick?" Or once he starts slowing down, "Old Slow?"
When Scott Stewart speaks I go for the mute button. This has been my habit for about 15 years now. I will not accept "Young Quick" as a nickname.
I really like the Afterburner, perhaps shortened to "The Burner". Also, "Rufus": Chris Rock's character, the 13th Apostle from Dogma, cause he was sent by a higher power (Morey) to lead the way. Chris Rock is a pretty damn good nick, though. Kinda like Mike "Omar Epps" Tomlin, or Bill "Sgt. Slaughter" Cowher.
