Fatassing

When people (especially cops) stand around not doing their jobs but instead eating food and/or drinking coffee.

Joe: Wow, this traffic is really backed up. You'd think the cop would be directing all the cars.
Billy: No, he's too busy fatassing. Look he's got a donut in one hand and a coffee in the other!
