I came here with the same question and here is what I've found: https://forum.duolingo.com/comment/22698756/differences-between-ute-and-utenfor
Can anyone tell me de difference between 'ute' and 'ut'? I was watching this Norwegian show with English AND Norwegian subtitles so I could learn the language better and then there's a line when the boy is asking to his friends get out and he says "Ut, ut, ut!" like "Out, out, out!" While here we learn 'ute'. Is there a difference, really?
To watch with Norwegian subtitles I watch on the official website skam.p3.no/episoder/ but with English subtitles you have to download on Google Drive (some people post on their drive). I think this link still works but I'm not sure drive.google.com/drive/folders/0B3KyatFgRTdrbTVaaGdvSEhlZnM
