I only found out today that the term Social Butterfly refers to someone who is outgoing and loves social events. I thought it meant you didn't like social events, as in you would fly away and avoid them. I also until recently thought that a Spendthrift is somebody who is frugal in their spending. I assumed that as thrifty meant not being wasteful, that Spendthrift meant being careful in what you spent.
YANBU..I see where you are coming from.
YABU.. You are a wally, go back to school!
