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!"

silent scope

An arcade-style game that is usually accompanied with a sniper rifle. You have limited life and limited time to take out all targets on the screen.

Your usual objective is to take out enemies, key targets, or carefully eliminate the character while he/she has a hostage.

To have the utmost experience of sniping, always play at an arcade; Controllers just don't cut it.

Tap Dancer: Wanna play DDR? LOL!
Rifleman: Pfft, screw that game. I'm heading over to the Silent Scope area.
