quite often used when bored out of ones mind when stuck at work;
also when pissed off at boss due to something they f***ed up and now you have to fix;
this could also come from a subordinate that you will later fire for the incompetence

asdfjkl; is called the home row of the standardized keyboard. You place each of your fingers on each key in order to type correctly and easily do it using muscle memory. Its also what you type when you're really fucking bored.
John: Hey i don't like porn i'm going to finger my keyboard instead.
