Being gr00bered mean being a victim of gr00bering, a form of sophisticated internet trolling where the troll appears to be a newbie and then lures the resident experts into wasting lots of time on mindless questions.
Proper gr00bering is done with style and humor, such as asking how to write an operating system in JavaScript (though not directly, but after a lengthy introduction to establish genuine newbieness)
When someone grabs a guy'sballs from behind, in between his legs, and lifts. The guy is suspended in the air momentarily and isn't sure what to do. Usually, he jumps.
That guy just got gobblered, he didn't even know what to do!!!!!!
