Hangry and smad
There are surely more examples of these blended portmanteau emotions, but “hangry” (hungry + angry) has become a major part of my kids’ lexicon, and “smad” (sad mad) was made memorable by a mention in Gilmore Girls.
I find hangry in particular quite useful as a reminder to check for HALT (Hungry Angry Lonely Tired) when feeling off-kilter.
Maybe we should make a list here of the other words in this category.
