Freudentisch and What?

What is freudentisch? First impressions are, after all, very important, and I wanted to see what impression people had when all they knew was the brand name. So I went around campus today and asked people to tell me if freudentish was a noun, adjective, or verb, and then I asked them to put that word into a sentence. It was more a game than anything, and since people recognized that they didn't know what it meant (and that it wasn't even English!) they relaxed and compliantly played along, coming up with random sayings and using freudentisch to replace words in common English phrases. Some even ventured to give me a direct translation.
