fumming 

The act of being fummy. To bludge. What one does at work after Friday's pub-lunch. Doing bugger all and dragging everyone else down with you.

Another, less common, form of fumming involves sitting next to a colleague while he is on the phone to a customer and scrawling all over his notepad whilst giggling. The notepad should end up containing a crude caricature of the colleague's sister with the words, "Please wear pants to my party" in a speech bubble. This slightly more obscure form of fumming can often be the most effective as both parties usually end up imploding in a fit of giggles.

The Letter M: "So, Soulless Ginge, what have you done today?"
Soulless Ginge: "Nothing mate. I've been fumming all day today."
The Letter M: "Okay. Let's sit around with Angry Italian and make knob jokes."
