To take the last of the coffee and not make any more for your coworkers. Describes the mix of frustration, anger, and resignation as you look at your cream ("cram") filled coffee mug while hefting the bone-dry ("bone") empty pot.
"Aw, man! I really wanted some coffee, but John cramboned me." "I was going to make more coffee but I was in a hurry, so I just cramboned everyone."
