Silent-Laugh Mode 

The state one enters during a fit of uncontrollable silent laughter.

"Did you hear what happened to Stacy's cat?
"haha yeah I told Steve and he immediately went into silent-laugh mode..."

silent laughter 

When something is so funny, or you are in a state of such slap happiness, that regular laughter transforms into an almost silent and uncontrollable activity. Usually accompanied by tears, silent laughter is most likely the best kind of laughter. You have to make a conscious effort to remember to breathe as your lungs lose air fast in the process of silent laughing. Your ribs start to ache and you begin to wonder if you'll be physically able to take a deep breath before resorting to more silent laughter. Friends and family may laugh at you in this state, or they may be joining in right next to you. Concerned strangers will stare at you and seriously consider finding you help, or they may just hide you from their children.

After I mentioned an inside joke, I looked over to my friend who was doubled over with silent laughter.

silent laughing 

Laughing so hard that the voice box shuts down and the body jerks around in spasmatic efforts to make a noise.

Anneliese, watching from her bed, was in the middle of one of those spasms of SILENT LAUGHING that wrack your body with convulsions and render you unable to make a single noise. You're like a whacked-out mime immitating a gleeful chimpanzee who just threw a handful of faeces at someone from behind the bars at the zoo.

silent laughing 

Laughing silently:

1) What you're probably doing right now if you're on this site reading definitions instead of doing your damn homework, and not supposed to be on the computer. Usually accompanied by snorts and gasps, as well as tearing of the eyes and spasms.
2) What you do when your friend's brother disses your friend real good, and you don't want your friend to get pissed at you for laughing your ass off.

1) Parent: "Son, what are you doing up there? What's so funny? You better not be on that Urban Dictionary site!"

Son: "*buckling with silent laughter* Sh-hart! Ha ha ha ha...!"

2) Brother: "Go give Kevin's sis a hot Carl, you fucking SP.ED."

You: "Hee..Hee...*silent laughing*"

Friend: "What the fuck are you laughing for, get the hell out of my house!"
