A map in the Counter Strike Series in which players are only allowed to have a Knive and a Scout.
Most "SK" players learn how to do a trick called "sky strafing" which enables you to glide through the sky.
The second talent most "SK" players need is to beable to "noscope" which is shooting the enemy without croosshairs.
CS:S player1: "Wow he can noscope so well in scoutsknives!!"
CS:S player2: "Yah he probably painted a dot on his screen to know where the crosshair is that nerd!"
