Noobacker

Any person who succesfully hacks a website, but after a security upgrade, can no longer do so.

That Noobacker on our site was really annoying. The admin got a new security system and he's gone now.

Nooback

One who goes AFK during a game and comes back in the midst of everything, who ends up getting pwned.

"Hey, what'd I miss? Oh shoottt... I missed the raid. I'm going to go ahead and pop in as we win."
"You nooback."
