Short for Expelling Air Silently. Represents the action of being unable to stop laughing, but not making any sound, so as not to alert others to one's own amusement. Used in place of LOL in situations when laughing out loud would be impolite/unacceptable, such as the workplace.
A friend linked me to a funny picture, but I had to EAS so my boss wouldn't wonder why I was laughing alone at my desk.

The EAS (Emergency Alert System) Was Developed by the United States Government, in 1990's to Enhance how Emergency Warnings would be transmitted,
Before the EAS Was the EBS, or Emergency Broadcasting System, the Successor to the CONELRAD Radio Alert Network.

EAS Transmissions have been revised Time and Time Again, The Latest Visible Revision to the EAS, is that it now uses a Black Background and White Text Scheme. The EAS Has Been Used For Several Events, such as Tornadoes, Hurricanes, Severe Thunderstorms, And Civil Emergencies, such as Terroristic Attacks.
The Most Known Feature of the EAS is the "Noisy" Tones it makes at the beginning of the Transmission: SAME Tones, which are actually Encrypted Messages.
{SAME Tones}
{1280Khz Warning Tone}
This is a Test of the Emergency Alert System.
If this were a Real Emergency, information about the Emergency would be Displayed on Screen.
This is only a Test.
{1280Khz Warning Tone}
Tom: Well, i'm Glad that EAS Test is over.
