Grundiegreu

Grundiegreu. A snack or dessert made by mixing peanut butter, honey, and powdered chocolate until the consistency is that of peanut butter. Can be eaten in a variety of ways but is generally limited to hot, cold, with ice cream or frozen.

Tonight I shall be lazy and make grundiegreu instead of an actual dessert.

Grundiegreu is better than chocolate sauce because it has peanut butter in it.

Green Grungies

When the food that has been consumed causes your stool to have a very distinct green color. Defacating a Green Grungie can also include discomfort, wetness, and/or strong odour.

Low grade meats and high grease content have a higher likelihood of causing Green Grungies to form. (McDonalds, KFC, etc.)
