When one is feeling a sense of disappointment, but it seems to be more. This person is also feeling sorrow. The feeling is often undescribable and confusing. Once understood, is later followed by a feeling called konfussted. Dissoreque is a combination of the words disappointment and sorrow. The "esque" at the end is simply added to make it sound better.
After I found out that Carolina and Charlie had had sex, i was feeling pretty dissoresque.
