knocking off 

Fumbling about and goofing off, being as unproductive as possible, usually when something important needs to be done such as filing the paperwork Johnson handed you before lunch.
Also can refer to when someone is annoying the shit out everybody within a 50 foot radius, all the while thinking they are in fact making others laugh.

"Man we need to get this project finished, ASAP"
"Yeah but we'll never get it done, Zack is over there knocking off."

(Kid is dancing down an obviously crowded hallway and bumps into someone trying to mind their own business)
"Hey man quit knocking off!!!"
