Gluberstienstchen
Gluberstienstchen: A term used to describe the feeling of intense focus and productivity while writing, often resulting in a large amount of high quality work being produced in a short period of time. This term is derived from the German words "gluber," meaning intense, and "stienstchen," meaning focused work.
I was in the zone while writing my paper last night and had a serious case of gluberstienstchen. I ended up finishing it in record time and getting an A on it.
