a newb
A newb is someone who's barely in the game and might get better. But don't count on it. They're just a step up from a noob, who gets tossed out like garbage.
"Newb? I was a noob last week.", A guy who just finished his first level.
"I'm a newb, not a noob, I just need one more chance.", A kid who got knocked out 3 times in a row.
"Newb? I'm a newb, I just got here.", A guy who joined the game 5 minutes ago.
