After engaging in anal sex, the penis is dressed like German dish with sauerkraut and German toppings alike. The other individual performs fellatio on the German dish, which tastes similar to a regular German meal.
Most common toppings; Saurkraut, spicy mustard, cheese, and semen (best served hott)
Works well when accompanied with a Shitler (see term for more details)
