(a fusion of joy and happy): when you are happy because someone else is happy, also called sympathetic joy. Other languages have a word for it already, e.g. mudita in Sanskrit
Look at the happy couple. Aren't they great? It makes me feel so joppy.
A descriptive word that came from a mispelling of jolly. It brings a positive connotation to any sentence: a mix of the words "joy" & "sloppy". Now used practically in anyway by young adults mostly in theatre.
