What is Friendvious?
1.
happy that your friend has something worth envying - in other words, jealous of something your friend has, but conversely glad that she/he has it (i.e. wishing that theoretically there were some way that both of you could have it at the same time)
"I am totally friendvious of your purple houndstooth jacket that you found for $18. I mean, it looks awesome on you...."
