a grumpopotamus what one would refer to their spouse or partner when they stomp around and grunt as the only means of communication when diplomacy is needed. this is the act of being distant, hung over, hungry, sleepy, drained, emotionally compromised and not talking about whatever it is. ultimately just picking a battle or argument for no good reason with someone when they should be having fun.
