Gibbing, deriving from the word "giblets" meaning the offal of a dead animal, is a video gaming slang term featuring prominently in many 3D shooter games.
The word refers instances when a game character has been killed with such force that their body explodes leaving their "giblets" visible all over the floor.
While playingDoom 3, I'm going to give all the newbies a really good gibbing!
It is where you cant stop talking and blurting out sayings from the SNL skit "The Barry Gibb Talk Show" which is a great parody of the brothers Barry and Robin Gibb of the Doobie Bros. (aka Jimmy Fallon and Justin Timberlake)
Blurting out "aaaagghhhh" and "Do you have anything to aaaad" in a shreiking voice likeBarry Gibb! Out of nowhere I pulled a Gibbisms in the bar when I talked to that chick!
