The melancholy emotional hangover that occurs after being around family. Particularly applicable if you are in recovery and your family is not. But can be used simply to describe the fog of defeat you feel when being exposed to criticisms or feeling unworthy after being with family. Makes you doubt yourself and feel sad that the relationships aren't in a better place.
Still feeling my fangover from Thanksgiving dinner where my mom was criticizing me and bragging about my sister's.
Massive fangover from the family reunion where there was too much one-up manship and comparison about careers/incomes/accomplishments.
I have a fangover from the weekend because I wish I was in a better place with my sisters.
A super bad hangover. Similarly to 'fugly' or the combination of 'fucking' and 'ugly'...'fungover' is the combination of 'fucking' and 'hungover. This shortened version takes out the extra word and thus reduces the amount of work it takes to express just how bad the morning after is.
