Sack of Flour 

A typical friend who lays on their ass all day pretending to do "other things" rather than actually perform some productive task. This friend may make excuses of homework, school, alternate activities, time-consuming single player games, et cetera. In reality, they are likely sitting on their couch watching TV.

You: Hey, (name), you want to go play paintball or game this weekend?

Friend: Nah. I've got a test to study for, a few papers to write, and a bunch of other things that piled up suddenly.

You: Why are you being such a sack of flour, I know you don't have any shit to do...
