MGO 

Short for "Metal Gear Online". MGO was offered for one year after the release of "Metal Gear Solid 3: Substance".

Now, MGO is back in the game "Metal Gear Solid 4: Guns of the Patriots".

Have you played MGO lately?

Yes I have, I came in number one during a Death Match.

Moderate Giggle Out Loud.

When LOL just isnt an accurate description - its funny - but not that funny.

Julie thought she was funnier than she was, but I didn't want to offend her so i just did a MGOL.

Adam: I just spilt milk on myself
Luke: MGOL! Clumsy!

Wanda: That movie wasn't as funny as I hoped...
Sandy: It was more mgol than lol
