der-brain
Any child whose brain is full of der. 'Der' can cause you to do stupid things. The word der, and its variant der-brain (or bwain) was pronounced "duuuhhhhhhhh" in a mong voice at a length directly proportionate to the idiocy of the addressee. Usually used in response to someone acting like a div (q.v.), it was the voice of scorn descending on the unfortunate transgressor. More effective in choruses of 10 kids or more.

One boy at our school was deemed to be so much of a der-brain that he actually beamed rays of pure der, like a lighthouse.

Deciding that "Der-Ray Flasher" sounded like the name of a country and western singer, we wrote his eponymous debut song. Well, I say a song, but it was more along the lines of pretending to play the banjo and singing "I'm Der-Ray Flasher" in cod-American twang.
