Hi c_b, I'm a big fan of your lists. Essentially yeah, humans essen and animals fressen. So if you use fressen in terms of people it suggests they eat like animals, hence a figurative meaning akin to gorge or devour. The party just came to mind because there was a lot of food and I probably ate too much, and yet when I was chatting to Andrea on the stairs I felt like gobbling her up too. I've seen fressen somewhere in print in an English piece recently which is why I added it. I'll quote it when I can find it.
I do know this word, but I haven't been to said house party. Your comment makes me wonder what alternate meaning this word has that I don't know. I thought it was "to feed," as in "to eat," but only used to describe animals....?
A bit German but I'll take it. If you don't know this word you probably haven't been to a house party on a Saturday night in Leipzig with a gorgeous girl making eyes at you on the stairwell around midnight.
