Over Encumbered means in slang: 1. When your mother or girlfriend makes you take all her shopping. It’s too heavy, even if it weighs three ounces. 2. When you are feeling suicidal because of the circumstances of the day, but too exhausted to get out of your misery. 3. When an excessive amount of items in your tiny backpack makes it impossible for your character to move. Not all RPGs allow for slow movement while being overly encumbered. However, it is so slow that you may as well be still standing. (in Slang Dictionary, added by Lainey Tucker)
