What about giving a name to a thousand noobs, since that denomination is frequently used? Yeah, it's short-handed as 'k' but, I'd like to buy a stack of diamonds for 12 Knoobz (with the 'k' pronounced-- "kuh-noobz"). Or maybe 12 Groobz ("grand" + "noobz").
"Knoob" sounds so Jedi-ish. A charm for mind-tricking the seller to lower the price? Lol
