A nickname for someone who has a large forehead, and if you know German because I don't, you probably know that the word "herr" is a title equalivent to "Mr." So, in conclusion, the words "Herr Forehead" just mean Mr.Forehead. But don't go calling random people that! This name is reserved for glimmerous prosecutors who enjoy fighting a specific male lawyer with antenna hair, (aka homosexual flirting) calling him by the nickname, and playing the guitar. They also tend to have lots of fangirls. But believe it or not, they actually respect them.

translations:

おでこくん - Odeko-Kun(Japanese)
大脑门君- Big-Forehead kun(Chinese)
"You're thinking out loud, Herr Forehead. Here, let me buy you dinner to make up for it."
