An emoti-acronym used for situations where "LOL", "LMAO", and/or "ROFLMAO" just doesn't quite express the fit of laughter you are experiencing. "GMB", or "Grabbing my balls" can be added to any of the aforementioned to adequately illustrate your uproarious reaction to what you have found to be overwhelmingly funny. Additional intensity could be expressed by adding an 'F' -- such as: "GMFB".
"LMAO GMB!! That's fuggin' classic!"

"What? She got caught jerking off the janitor?? LOL GMB!!!"

It means "Google Me, Bitch!" It's used when someone questions your identification when they should know you because of your level of fame.
