"AWDS" are the most used keys in PC games, especially in FPS's and RP games.
The keys are laid out and pressed like this:
Q 2 E
1 4 3
Respectively it is the left hand layout: 1=ring finger, 2=middle finger, 3=index finger (respectively), and 4=middle finger (after pressing 2).
Usually in these games these keys are pressed when the player is about to reply to a message but soon becomes busy and can not reply with a proper message, FORGETS TO DELETE/SEND MESSAGE AND IS TRYING TO FIGURE OUT WHY HE CANNOT MOVE! :O ... then realises :/
Because the player is pressing all those keys so many times it can look like this: awdsawdsawds
(sometimes jumbled but also this makes "sawd" - just another way of saying this combination)
In game Nub: Oi! you there?
